MDPI Insights: The CEO's Letter #9 - Romania, Research Integrity, Viruses

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Reka Kovacs (Deputy Office Manager, MDPI), Stefan Tochev (CEO, MDPI), and Sandra Ana Spatariu (Office Manager, MDPI) at the MDPI office in Cluj, Romania.
MDPI’s Impact on Romania
In February, I visited our office in Cluj, Romania. I worked closely with our senior office managers and various teams, including the departments of training, marketing and conferences, as well as our journal relationship specialists, reviewing our service to the local scholarly community. During the visit, I also met with representatives from Babes-Bolyai University and the Technical University of Cluj-Napoca. Our multifunctional Romanian office plays an important role in supporting our collaborations with the local market as well as helping to meet MDPI’s overall business needs.
Feedback and strategy meeting with a group of MDPI’s Journal Relationship Specialists at the MDPI office in Cluj, Romania.
With 22,436 articles, Romania ranks as a top 20 contributing country to MDPI’s total number of papers published as at 28 February 2024. This highlights the importance of our collaboration with Romanian-affiliated authors and the growing opportunity to support their publishing needs. MDPI is one of the few academic publishers with a significant presence in Romania, boasting over 360 colleagues across our offices in Bucharest and Cluj. We are also proud to hire colleagues from local institutions to launch their careers within publishing.
Romania ranks as a top 20 contributing country.
The Numbers: 2019–2023
MDPI has seen a healthy increase in submissions from Romanian authors over the past three years, from 8,439 in 2021 to 11,866 by end of 2023, with most submissions going to journals such as Sustainability, Medicina, Diagnostics, IJMS, Applied Sciences, and JCM. From 2019 to 2023, MDPI published articles from 32,145 authors affiliated with Romanian institutions. Over those years, we have worked with Romanian Guest Editors on nearly 3,000 occasions to support their Special Issue and Topical collections.
With more than 300 Editorial Board Members from Romania, 34 appear on the board of Mathematics, 27 on Materials, 19 on Polymers, 18 on Coatings, and 16 on Molecules, while three serve as Section Editors-in-Chief (SEiC) on our journals Coatings (3.4 IF, 4.6 Citescore), Magnetochemistry (2.7 IF, 3.5 Citescore), and Chemosensors (4.2 IF, 3.9 Citescore).
Institutional Open Access Programs
Our commitment to working with institutions is evident in Romania, where we have established eight Institutional Open Access Programs (IOAP) with esteemed institutions such as the University of Bucharest, the University of Medicine and Pharmacy Cluj-Napoca, and most recently the National Institute for Laser, Plasma and Radiation Physics.
Our growth and presence in Romania are a true testament.
We also have IOAP agreements with Babes-Bolyai University and the Technical University of Cluj-Napoca, where I had the opportunity to meet senior stakeholders during my visit. Below are a few photos capturing our meeting with Prof. Radu Silaghi-Dumitrescu (Head of Faculty of Chemistry, Babes-Bolyai University) at the MDPI office in Cluj, Romania, along with a photo from our meeting with Vice Deans Nicoleta Cobarzan, Nicoleta Ilies, and Hoda Gavril, from the faculty of Civil Engineering at the Technical University of Cluj, Romania.


Our growth and presence in Romania are a true testament to the service we provide to the scholarly community and the relationships we foster in that region. We look forward to continuing to support Romanian scholars and institutions by providing a valuable and trusted experience with MDPI, the leader in open access publishing.

Please click here to access everything that you need to know about MDPI’s Research and Publication Ethics.
With this span of complementary roles, the RIPE team collaborates directly with journal editorial teams and works closely with various departments, including our Scientific Office Board and our Journal Relationship Specialists. The team’s primary objectives are to help prevent issues regarding research integrity and publication ethics during peer review, uphold MDPI’s ethics policies, adhere to industry standards, and resolve publication ethics and research integrity issues and complaints.
Quality Updates to Special Issues Oversight
At MDPI, we are committed to reviewing policies pertaining to the quality of research. In this blog post, Shaheena Patel (Communications Associate, MDPI), outlines two recent updates to MDPI journal processes. These updates pertain to Special Issue (SI) quality guidelines, in line with criteria provided by COPE and DOAJ. Alongside the SI updates, details regarding the new minor corrections policy introduced in 2024 are provided in the blog.
The two updates we implemented include greater oversight and the verification of Guest Editor credentials. These guidelines require that Editors-in-Chief (EiCs) and Editorial Board Members (EBMs) take responsibility for overseeing SIs.
PS. Thank you, James Butcher, for featuring this up in your 67th issue of the Journalogy newsletter.

Closing Thoughts
Researcher to Reader (R2R) Conference
From 20–21 February 2024, I had the pleasure of attending the Researcher to Reader (R2R) conference in London, which MDPI has proudly sponsored over the years. The conference programme offered a variety of session formats, including workshops, panel discussions, debates, interviews, presentations, and lightning talks, with opportunities to discuss relevant topics.
We take pride in supporting the scientific community, bringing researchers across the world together to network, exchange ideas and share the latest in science and publishing. In 2023, MDPI invested close to 2 million CHF in sponsoring over 2,000 scientific and publishing-related conferences worldwide.
R2R Peer Review Innovations Workshop
I found the R2R conference to be engaging, with the workshops being particularly enjoyable. My colleague Giulia Stefenelli (Chair of Scientific Office Board) and I participated in the “Peer Review Innovations” workshop, which spanned four sessions over the two days. These sessions explored the future of peer review and how we can improve the peer review process for everyone involved. Notably, the large majority of attendees expressed their opinion that peer review, as currently practiced, requires significant improvement. Together, we collaborated on potential immediate and long-term improvements and innovative processes, aiming to create an ecosystem beneficial to all stakeholders by strengthening submission systems with the aim of reducing threats and making authors more responsible for their work. We also discussed the opportunity for academic institutions to better scrutinize the quality of the work produced and submitted to journals.
Our group comprised publishers, software providers, librarians, and more, bringing diverse perspectives to the discussions. These interactions were relevant to MDPI’s ongoing conversations, providing insights to our efforts. The session also made me appreciate that MDPI is doing well, as the group discussions included the subject of various quality checks that we have already embedded in our processes, ensuring that we keep abreast of industry standards.
The need for an optimized system to incentivize the activities of editors and reviewers was also a focus of discussion, as well as the support that reviewers need from publishers via the provision of strong reports through fixed forms, questionnaires and training.
At MDPI, we are currently auditing our reviewer program to improve reviewer recognition, guidelines, and methods for identifying suitable reviewers, while maintaining our commitment to quality and timeliness.
Congratulations to Mark Carden, Conference Director, and the R2R team for organizing a productive and successful event. PS: The break times were greatly appreciated as well!

MDPI Insights: The CEO's Letter #8 - Altmetric and Flat Fee Agreement

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
MDPI and Digital Science Meeting
At MDPI, we are committed to providing our authors with the essential tools to publish, promote, and track their research. In line with this commitment, we have established a longstanding collaboration with Digital Science, a company specializing in research data and analytical insights for the research community. Our collaboration integrates their Altmetric tool, offering us and our authors the ability to track a variety of sources that monitor and report attention surrounding publications.
As part of our collaboration, we recently hosted Cathy Holland, Director of Global Publisher Business Development, and Helen Cooke, Managing Director of Publisher Sales, from Digital Science, at our MDPI headquarters in Basel, Switzerland.
Left to right: Facundo Santomé (Senior Marketing Manager, MDPI), Constanze Shelhorn (Indexing Manager, MDPI), Cathy Holland (Director of Global Publisher Business Development, Digital Science), Helen Cooke (Managing Director of Publisher Sales, Digital Science), and Stefan Tochev (CEO, MDPI) in front of MDPI headquarters in Basel, Switzerland.
During our meeting, we discussed MDPI’s publishing philosophy and explored further avenues for collaboration. We look forward to continuing our partnership with Digital Science, aiming to improve our services yet further and meet the needs of our authors more closely than ever.
What is Altmetric?
You will notice that MDPI articles feature an Altmetric score, a colourful doughnut capturing the score in the upper right corner of the article page. This score represents ‘alternative metrics,’ as distinct from traditional metrics such as Impact Factor, CiteScore, and Scimago Journal Rank.
Altmetrics complement traditional citation-based metrics by capturing online discussions related to a specific research topic. By analyzing both sets of data, we can obtain a comprehensive understanding of the attention a particular research output receives and the sources in which it is mentioned.
“Almetric provides visual insights into where research is being discussed”
Sources Tracked by Altmetric
Altmetric badge showing the Altmetric score and colour-coded mention sources.
Altmetric monitors various sources, categorizing them into segments such as policy documents, peer reviews, Wikipedia, news and blogs, and social media, among other sources. Each category is identifiable by a specific colour.
The Altmetric badge provides visual insights into where the research is being discussed. A more colourful badge indicates broader mentions across multiple platforms. Such tracking enables us to gauge the extent of an article’s online dissemination, noting that increased visibility may correlate with higher citation rates.

MDPI Annual Meeting Celebrations in China
On Thursday 25 January, over 1,300 MDPI colleagues from our two offices in Beijing gathered to kick off MDPI’s traditional ‘Annual Meetings.’ These celebrations take place in MDPI’s offices across China, including Dalian, Tianjin, Wuhan, and Nanjing.
The evenings include performances, informative talks and presentations, awards, and entertainment, providing an ideal platform to recognize our colleagues, celebrate their achievements, and set our sights on the future.
“It is essential that we stay connected and share best practices”
I sent a video congratulating everyone on their work and sharing our vision of building MDPI into the most trusted OA publisher, highlighting the roles each of us has to play in achieving that goal.
Unfortunately I could not join in person, but you may recall my recent trip, when I visited our offices in Beijing and Wuhan, which I look forward to visiting again this year.
Although our headquarters are in Basel, Switzerland, and we are expanding throughout Europe and North America, the majority of MDPI’s workforce is in China and throughout the Asia-Pacific region, including offices in Singapore, Thailand, Japan, and newly opened office in South Korea. It is essential that as a global organization, we stay connected and share best practices in order to grow collectively and continue providing the exceptional service to our authors.
The Annual Meeting is a moment to reflect and enjoy the year’s hard work and dedication.
I extend our best wishes to all for the Chinese New Year (Xīnnián kuàilè)!

APC discounts and Book Processing Charge discounts are available for affiliated authors. Automated deposits to institutional repositories and streamlined matching of papers to IOAP participants enhance the overall experience.
For further information, see our IOAP FAQ.
Closing Thoughts
Reflections on the 2024 APE Conference
MDPI was proud to co-sponsor the Academic Publishing in Europe (APE) 2024 Conference that took place in Berlin, Germany, from 9–10 January 2024.
The conference theme, ‘Keep the Conversation Going!’, explored the evolving landscape of scholarly communication. APE is one of the key conferences I make a point to attend each year. January offers a valuable opportunity to engage with new contacts, reconnect with familiar faces, and participate in impactful discussions and presentations among professionals, scholars, and practitioners in the field.
“It's fascinating to see how other publishers are leveraging AI”
Highlights
Some of the standout panels for me include: the role of the UN Sustainable Development Goals (SDGs) within the publishing industry. It was encouraging to hear the current status quo, though I was eager also to learn about the exciting projects planned for 2024 and beyond. These will allow us to track progress in subsequent years. At MDPI, we remain committed to promoting Open–Access (OA) content on SDGs through scientific articles and books. Furthermore, we extend our commitment to sustainability by financially supporting researchers through initiatives such as the World Sustainability Award and the Emerging Sustainability Leader Award, as well as waiving the APC for feature papers on each SDG.
In recent years, discussions on AI have become increasingly prominent at such conferences. It’s fascinating to see how other publishers are leveraging AI to meet the evolving needs of their audiences while at the same time using it to safeguard the scientific process. Other engaging panels that I enjoyed included updates on transformation beyond transformative agreements, the principles of lean change, incentive structures related to research integrity, and the panel on reviewer incentives.
“We can share best practices and lessons learned”
Incorporating MDPI’s Insights into Conferences
I must confess that I sometimes feel overlooked when MDPI is not invited to participate in crucial industry discussions. As the leading open access publisher and the third-largest publisher overall, we possess extensive experience in many of these areas and can offer valuable contributions to these discussions. We can share best practices, lessons learned, and our thinking about future trajectories. For instance, in panels discussing reviewer incentives, at MDPI we offer a discount voucher to reviewers for future submissions, reflecting our commitment to fostering a robust peer review process. In 2022 alone, MDPI collected over 1.4 million peer review reports, informing the decision-making processes of our editors. Given our expertise in these areas, it would be natural to include MDPI in such discussions. I therefore extend an invitation to future conference organizers to consider MDPI for speaking engagements and collaborative opportunities.

MDPI Insights: The CEO's Letter #7 - Nobel Laureates Entrust MDPI with Their Research

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Nobel Prize Laureates Entrust MDPI with Their Research
The Nobel Prize stands as a hallmark of distinction, honouring ground-breaking research across disciplines. Annually, the Nobel Prizes are awarded in six categories: Physics, Chemistry, Medicine or Physiology, Literature, Peace, and Economic Sciences.
Through the years, renowned scholars have entrusted MDPI with their work. As at December 2023, 26 Nobel laureates have contributed to more than 75 articles across 25 MDPI journals, including: Antibiotics, Applied Sciences, Biology, Biomedicines, Cancers, Catalysts, Cells, Crystals, Entropy, Games, IJMS, Life, Materials, Micromachines, Molecules, Pharmaceuticals, Pharmaceutics, Photonics, Quantum Beam Science, Remote Sensing, Sensors, Solids, Universe, Vaccines, and Viruses.
The best of the best trust us with their work.
Nobel Prize Laureates Who Have Published with MDPI
We are proud to list the names of Pierre Agostini, Hiroshi Amano, Werner Arber, Aaron Ciechanover, Robert H. Grubbs, Oliver Hart, Gerard ‘t Hooft, Michael Houghton, Harald zur Hausen, Katalin Karikó, Jean-Marie Lehn, Gérard Mourou, Ferid Murad, Shuji Nakamura, William Nordhaus, Kostya S. Novoselov, Giorgio Parisi, Charles M. Rice, Alvin E. Roth, Donna Strickland, K. Barry Sharpless, George F. Smoot, Anne L’Huillier, Drew Weissman, Kurt Wüthrich, Ada Yonath.
The privilege of hosting such contributors resonates deeply with our editorial teams. For instance, in this interview, the Editor-in-Chief (EiC) of Universe speaks on the significance of publishing a paper by Nobel laureate Gerard ’t Hooft within the journal.
2023 Nobel Prize Winners Published by MDPI
Nobel Prize Winners, 2023: Katalin Karikó, Drew Weissman, Anne L’Huillier (Ill. Niklas Elmehed © Nobel Prize Outreach)
Three laureates from the 2023 Nobel Prize cohort have trusted MDPI as their publishing platform. Notably, in a 2022 Pharmaceutics paper, molecular biologist Katalin Karikó and her team presented a methodology for evaluating mRNA capping efficiency, pivotal for therapeutic applications. Pharmaceutics had previously dedicated a Special Issue to “mRNA Therapeutics: A Themed Issue in Honor of Professor Katalin Karikó”, spotlighting ten articles from August 2021 to February 2022.
In the journal Vaccines, Professor Drew Weissman, collaborating with scholars from Pennsylvania University and George Mason University, contributed an influential review titled “Nanomaterial Delivery Systems for mRNA Vaccines”. His collaborative efforts spanned five papers across MDPI journals between 2021 and 2023.
Furthermore, Anne L'Huillier of Lund University, only the fifth female recipient of the Physics Prize, co-authored an article in Applied Sciences focusing on "Advanced EUV and X-Ray Optics". Similarly, Pierre Agostini, an Emeritus Professor from Ohio State University, co-authored an article featured in the special issue "Attosecond Science and Technology: Principles and Applications".
We extend heartfelt congratulations to all Nobel Prize laureates and express sincere gratitude for their confidence in MDPI as a platform for their scholarly contributions.

Impactful Research
MDPI Journals Newly Indexed in 2023
The aim of indexing is to enhance the quality and credibility of published research, ensuring that researchers access the most credible resources available. While the principle behind citation indexing is straightforward, it remains one of the most dependable methods for tracking an idea's evolution across various scientific disciplines.
Throughout the year, MDPI works to expand the reach of our publications across premier multidisciplinary databases like Web of Science, Scopus, EBSCO, and ProQuest. This initiative is spearheaded by MDPI's Indexing team, under the leadership of Dr. Constanze Schelhorn.
In 2023, MDPI achieved 54 new acceptances in Scopus, 29 in Web of Science, 52 in EBSCO, and 83 in DOAJ: Directory of Open Access Journals.
The team prioritizes ensuring that our journals feature in numerous specialized databases, including PMC, PubMed, MEDLINE, Inspec, CAS, and FSTA, among others. Currently, MDPI collaborates with over 65 renowned international databases, consistently enhancing our database affiliations annually.
MDPI’s journals are indexed in all major global databases.
Furthermore, we collaborate with universities and government organizations to list our journals in country-specific ranking lists and relevant institutional repositories. This ensures compliance with requirements often set by funders or institutions for authors to publish in specific journals.
Web of Science Adds 24 MDPI Journals to Emerging Sources Citation Index (ESCI)
Clarivate recently analysed MDPI’s new journals, resulting in 24 journals, mainly established in 2020, being added to the ESCI in November and December 2023. Additionally, five journals passed this assessment earlier in the year. For a complete list of our journals in Web of Science, refer here. Journals in the ESCI meet 24 quality criteria, ensuring editorial rigor. They may be considered for inclusion in broader indices like the Science Citation Index Expanded (SCIE), the Social Sciences Citation Index (SSCI), or the Arts and Humanities Citation Index (AHCI), based on four impact criteria.

Inside MDPI
MDPI Appoints New Chief Operating Officer (COO)
Alistair Freeland returned to MDPI and assumed the role of Chief Operating Officer in November 2023, a position he previously held from 2013 to 2019. He succeeds Dr. Yu Lin, who will remain a member of MDPI’s Board of Directors, overseeing significant financial decisions for the company. I would like to express my sincere thanks to Dr. Yu Lin for his service as COO.
Alistair brings extensive experience not only in scholarly publishing but also in technology and business management. Prior to rejoining MDPI, he was associated with SIX Group, the entity responsible for Switzerland's financial market infrastructure. There, he played a pivotal role in developing the blockchain-based platform SDX (SIX Digital Exchange), which has gained traction among major Swiss banks and the Swiss National Bank.
As COO, Alistair will collaborate with the MDPI management team to improve the practices and services we offer to scholarly communities. I am pleased to welcome Alistair back to MDPI and look forward to his contributions going forward.

Closing Thoughts
Reflecting on 2023 and Looking Ahead to 2024
As we approach 2024, I reflect on the incredible journey we’ve had together at MDPI this year. The past 12 months have been marked by ambitious projects and initiatives to improve our internal processes, and a commitment to continue delivering top-notch services to our stakeholders. I’d like to thank each and every one of our staff members for contributing to the positive experiences our stakeholders have reported in our surveys. Your dedication to speed, efficiency, and effective communication with our stakeholders is very much recognized and appreciated.
Becoming a stronger organisation
While we have encountered challenges in 2023, it’s important to understand that these are a part of our growth process. Difficulties provide us with opportunities to reflect, address problems at their roots, and ultimately evolve into a stronger organization. Our stakeholders expect us to overcome tough times, and it’s an expectation that we have for ourselves.
I extend my sincere appreciation to every MDPI employee, from our editorial office and IT department to marketing, indexing, IOAP, societies, Scientific Office board, products, production, conferences, finance, operations, admin, and beyond. To our newest team members, a warm welcome; to our longstanding colleagues, your dedication is invaluable.
“I am committed to taking MDPI to a new level of excellence.”
Interacting with many of you during my visits to our offices and representing MDPI at external events has been a personal highlight. I am deeply grateful to Dr. Lin for entrusting me with the role of CEO of MDPI. Looking forward, I am committed to working closely with our management team to lead MDPI and take it to a new level of excellence, aiming to establish it as the most trusted publisher in open access worldwide. This is a collective endeavour, with each of us shaping MDPI’s reputation. I therefore encourage us to take pride in our work, as it represents not only our craft but also MDPI as a whole.
Accountability and communication
As we look forward to 2024, there’s a lot to be excited about. Together, we’ll navigate challenges, seize growth opportunities, and refine our practices. To solidify MDPI’s position as the premier open access publisher globally, we must bolster accountability, improve stakeholder communication, share MDPI’s best practices, champion the open access philosophy, and educate stakeholders about our mission, methodologies, and motivations.
Thank you for engaging with the CEO Letter over the past six months of 2023. I will continue to release this newsletter as a method of sharing the great work being done at MDPI. Please feel free to connect directly with any insights or questions.
Here’s to a joyous and prosperous 2024!

MDPI Insights: The CEO's Letter #6 - MDPI Spain Summit and ResearchGate

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
MDPI Spain Summit
Stefan Tochev (CEO, MDPI) gives the opening speech at the MDPI Spain Summit.
On Friday 10 November 2023 I was in Barcelona, Spain, to deliver the opening presentation and participate in a panel at MDPI’s Spain Summit, a two-day event, inspired by our salon events in China.
With 16 Editors-in-Chief (EiCs) and 20 Editorial Board Members (EBMs) in attendance, the event, organized by our conference team and Barcelona office, featured presentations on open access (OA), MDPI, and publishing market trends in Spain.
The event provided a great opportunity to engage with stakeholders from various MDPI journals, including Nutrients, Vaccines, Buildings, IJMS, and others. We were able to gather feedback and have open conversations around manuscript quality, the peer-review process, and journal development, as well as accreditation agencies.
The main objective of this Summit was to bring together Editors representing MDPI journals across various disciplines within Spanish universities and research centers, primarily from the Barcelona area. The aim was to facilitate an open and fruitful discussion regarding the development of their journals, the future of OA in Spain, and to provide meaningful interactions and networking opportunities.
Connecting with Editorial Board Members
Stefan Tochev in conversation with Summit participants: "Our EBMs are passionate about the journals they serve."
Interacting with our EBMs in person provides a valuable opportunity to show how important it is to us to connect with them, hear their perspectives on their journals and learn more about their own experience collaborating with MDPI.
From my conversations, it was clear that our EBMs are passionate about the journals they serve. I know the advice they provide may sometimes involve just small tweaks, but these can lead to important improvements. As the saying goes, small hinges swing open big doors.
As at November 2023, MDPI has over 6,300 EBMs affiliated with Spanish institutions, with more than 30 of them serving as EiCs or section EiCs. Furthermore, over 68,000 Spanish scholars have contributed as reviewers in MDPI journals.
Open Access in Spain
In 2023, Spain implemented legislation mandating immediate OA for all publicly funded research, aligning with the EU’s Plan S initiative to expedite the transition to OA. The Spanish government also approved a four-year, €23.8 million annual budget for the first national OA strategy, aiming to make publicly funded research freely accessible upon publication. This strategy aims to strengthen the quality and transparency of research in Spain, and to help promote movement towards a digital, low-carbon economy.
For further details of Spain's OA policy and the history of government mandates, click here.
Spain has already seen a notable decline in subscription-only articles, decreasing by 62% over a 10-year period, while gold OA increased by 42%. Green OA slightly decreased, suggesting a shift towards publishing in gold OA journals rather than traditional subscription-based ones. Here are some statistics from Scopus.
A big thank-you to the various MDPI teams, including our conference team and the Barcelona office, for organizing this very successful event!
MDPI colleagues from various offices gathered to host and support the first MDPI Spain Summit, in Barcelona, Spain.
I think this type of gathering has the potential to become an annual event in various locations. For example, Manchester could be an option, as we have over 30 EiCs and over 3,000 EBMs in the UK, a top market for MDPI that publishes high-quality research.

Inside MDPI
Corporate Marketing and Communications Strategy Session
Members of MDPI’s Corporate Marketing & Communications team.
For the past few years, I have led the Corporate Marketing & Communications department in our annual strategy session.
This typically involves 2–3 days of focused sessions covering key topics including budgeting, hiring targets, campaign reviews, and planning for the upcoming year, department strategy, and structure.
We are constantly exploring ways to optimize the Corporate Marketing & Communications department to support MDPI’s primary objectives and better convey the MDPI story while serving the scholarly community.
The strategy session also serves as a team-building activity, during which the team voted on bowling!
Strategy Session
In this strategy session, we looked at how to align our teams in order to better streamline our content with our campaigns, build a dedicated marketing team to strategically support our core MDPI products, expand our communications teams and functionalities to focus on company-critical campaigns and press releases, align our new brand design system with our marketing initiatives, set up a community and engagement team to support various teams with their outreach and communication efforts, and increase our use of data in the evaluation of campaign performance.
To grow in these areas, we will be hiring for various positions, including those of Public Relations Manager, Communications Manager, Internal Communications Manager, Campaign Manager, Marketing Associate, and Editorial Engagement Manager.
I am grateful for the way our Corporate Marketing & Communications department has grown and gelled over the years, and I look forward to supporting the department teams and their ideas for the future.
Coming Together for Science
ResearchGate and MDPI Partner to Boost the Visibility of Open Access Content through Journal Home
Stefan Tochev (CEO, MDPI) and Sören Hofmayer (Co-Founder and Chief Strategy Officer, ResearchGate) meet in Berlin, Germany to take their ongoing discussion further.
When I assumed the role of CEO at MDPI, my primary focus was to initiate the building of essential partnerships and collaborations within our industry. After all, I am a firm believer in achieving our goals by helping others achieve theirs and focusing on co-opetition wherever there is an opportunity. I first touched on the notion of co-opetition in MDPI Insights: The CEO's Letter #3, particularly when discussing collaborations with Elsevier.
In light of this, Sören Hofmayer (Co-Founder and Chief Strategy Officer at ResearchGate) and I connected recently to continue a discussion that had been ongoing for months. I was quickly brought up to speed and felt there was an opportunity for MDPI journals to pilot the Journal Home service that ResearchGate had launched. This would provide a new way for MDPI to engage with authors and readers and amplify the visibility of our journals.
While I receive many offers and opportunities for discussions with vendors, I am a firm believer that timing is everything, and in this case, the time for us is now. Sören and I met in person during my recent visit to Berlin and decided to proceed with piloting ten MDPI journals with the Journal Home service.
The press release below provides further details.
Press Release: Berlin (Germany) and Basel (Switzerland), 15 November 2023
ResearchGate, the professional network for researchers, and MDPI, the largest open access publisher in the world and a pioneer in open access publishing, today announced a partnership that will see ten of MDPI’s open access journals benefit from an enhanced presence on ResearchGate through its innovative Journal Home offering.
This new partnership will expand the reach and visibility of MDPI’s participating flagship journals with ResearchGate’s highly relevant community of more than 25 million researchers globally.
Around 210,000 version-of-record articles from these 10 titles will be readily available on ResearchGate, including the full archive material and all new articles as they are published. These journals also benefit from enhanced brand visibility, with dedicated journal profiles, prominent representation on all associated article pages and all relevant touchpoints across the ResearchGate network – keeping the journals top-of-mind with their reader and author audiences. All articles covered by the new partnership will automatically be added to the authors’ publication records in ResearchGate. This not only reduces MDPI authors’ needs for direct management but also offers them valuable insights into the impact of their work, including data about readership and citations.
Closing Thoughts
November is Men’s Health Awareness Month
Stefan Tochev (CEO, MDPI) listening to music as he writes at a coffee shop in Basel, Switzerland.
November is dedicated to raising awareness of various men’s health issues. I have been fortunate to have positive male role models in my life, and I strive to share my experiences with others.
I used to take part in Movember, growing my moustache throughout November to raise awareness and funds and to help “change the face of men’s health.” With male family and friends impacted by physical and mental health issues, I have recently become more interested in men’s overall well-being.
Men often face stigma involving the perceived need always to be strong and have things figured out. Recently, I’ve had meaningful conversations with male friends and colleagues about issues we rarely discuss, and it was a positive experience.
Various factors impact men’s health and well-being, all too easily leading to risky health behaviours including a lack of health awareness, poor health education, and negative, culturally induced, behaviour patterns in our work and personal lives. I hope we can break down these barriers in our work environment.
Healthy men help build healthy families and a healthy society
Men are less likely than women to seek help with their physical and mental health struggles. This is a reminder to prioritize your overall well-being. I hope that as men, we will continue to open up to one another, becoming vulnerable in order to share what we are going through. By sharing and by supporting each other, we can learn and grow together. You are not alone, and when you fall, you can still get up and stand tall.
From one broski to another, you are loved and appreciated. I hope this mindset carries into December and beyond.
Mindfulness
Our content team recently released a handful of articles on mindfulness, a practice that I believe provides a good opportunity for stress release and self-reflection:

MDPI Insights: The CEO's Letter #5 - OA Week, UK, and Strategy

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Open Access Week 2023 – the Global Drive to Open Continues
As the world's largest open-access (OA) publisher, we believe that unrestricted access to research findings is the cornerstone of transparency, efficiency, and quality control across scientific disciplines. At MDPI, we provide free, immediate access to scientific papers, empowering scientists to examine, validate, replicate, and build upon existing results. This minimizes redundancy, optimizes resources, and fosters innovative approaches.
International OA Week, held from 23 to 29 October 2023, provided a unique opportunity to link the global movement toward open sharing and open science with the progress of policy changes at the local level. Our mission, during OA Week and all the year round, is to offer educational resources highlighting the benefits of open-access publishing. The MDPI Blog is a valuable resource for information on open access and open science.
Core principles of OA publishing
Accessibility, transparency, and collaboration are core principles of OA publishing. OA aims to break down barriers that have traditionally restricted research access, ensuring that knowledge is available to all, regardless of financial situation or institutional affiliations. Our commitment to diverse pathways for OA publishing worldwide includes discounts for researchers. You can learn more about how MDPI supports scientific communities here.
One of the key strengths of OA publishing is its ability to facilitate interdisciplinary research. By removing paywalls and promoting knowledge-sharing across disciplines, OA encourages collaboration and innovation. Researchers from various fields can access and build upon each others’ work, fostering a holistic approach to addressing complex global challenges.
OA holds the potential to democratize knowledge, advance science, and drive positive societal change.
Policy driving change
Governments, institutions, and funding agencies have recognized the transformative potential of OA and have implemented policies to promote it. These policies often require publicly funded research to be made openly accessible, accelerating the growth of OA repositories and journals. Check out our spotlights on OA policies in the US, EU and China.
OA publishing is continuously evolving, with community-driven models and technologies shaping its future. Initiatives such as “Plan S” and “cOAlition S” promote OA publishing from the perspective of national funders, requiring grantees to publish their research openly. A new policy announced by the US administration last year mandates that, with effect from January 2026, all US federally funded research should be freely and immediately available after publication.
Additionally, preprint servers such as MDPI's Preprints.org, which allow researchers to share their findings before formal peer review, have gained popularity, enhancing the speed at which new knowledge is disseminated. The rise of blockchain technology is also being explored to ensure transparency and authenticity in scholarly publishing.
For more than two decades, OA publishing has been revolutionizing academic publishing by promoting accessibility, transparency, and collaboration. Its support for interdisciplinary research, evolving policies, and innovative practices all contribute to its growing influence in the global research community. As OA continues to expand, it holds the potential to democratize knowledge, advance science, and drive positive societal change.
MDPI is proud to lead the transition to open access.

MDPI Strategy Meeting
As the newly appointed CEO, this is my first year leading the MDPI Senior Management Strategy session. I saw it as an opportunity to explore what MDPI has the potential to become in the next five years. Guided by the vision of its founder and President, Dr. Shu-kun Lin, the company has accomplished remarkable feats over the past 27 years and currently holds the position as the world’s third-largest academic publisher, following Springer Nature and Elsevier.
Our primary objective is to build upon the milestones of the past decades and consolidate MDPI’s position as well-established publishing brand. The two-day meeting emphasized the importance of communicating MDPI’s values more actively via its brand and adopting a straightforward yet impactful approach to managing MDPI as a mature academic publisher.
“Our primary objective is to consolidate MDPI’s position as well-established publishing brand”
As the world’s number one open-access publisher, MDPI has long been a game-changer in the scholarly community, serving millions of authors. The challenge in being a trailblazer is the need to continuously improve and at the same time explore the next blue-ocean strategy, while also maintaining the smooth operation of the business. Our collection model, featuring guest-curated thematic topics in the form of Special Issues, has disrupted the industry. Other publishers closely study us and attempt to replicate our models. The future of this collection model is something we are actively addressing – while, of course, looking ahead to what comes next!
