MDPI Insights: The CEO's Letter #10 - South Korea, IWD, U2A, Japan

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

Visit to Seoul, South Korea
During my recent visit to South Korea, I had the privilege of meeting various stakeholders, including representatives of government, research institutions, and academia, to understand their needs and communicate MDPI’s commitment to accessible science. Accompanied by my colleagues Dr. Giulia Stefenelli and Dr. Jisuk Kang, I engaged with the Korean scientific community, which is increasingly embracing open access (OA).
As the leading OA publisher in South Korea, MDPI is trusted by local authors and in 2023 enjoyed an approximately 30% share of the OA market. South Korea ranks sixth globally for MDPI in terms of research papers submitted and published.
MDPI and South Korea by Numbers
As at 30 March, over 76,000 MDPI articles have been authored by individuals affiliated with Korean institutions. We have over 1,800 active editorial board members (EBMs) from South Korea, with more than 880 EBMs having an H-index between 26 and 50, including 10 serving as Chief Editors.
“South Korea is the sixth-largest contributor to our total publications”
Over the past five years (2019–2023), nearly 120,000 authors affiliated with South Korean institutes have published with MDPI. Specifically in 2023, we received approximately 25,000 submissions from South Korean authors, publishing close to 13,000 articles, resulting in a rejection rate of 47.4%, which is not far below MDPI’s overall rejection rate of 56.4% in 2023.
Institutional Partnerships with South Korea
I am pleased to share that MDPI has more than 825 institutional partnerships worldwide, with 12 in South Korea, including Kyunghee University, Chung-Ang University, and Inha University, among others.
Left to right: Dr. Jisuk Kang (Scientific Officer, MDPI), Dr. Giulia Stefenelli (Chair of Scientific Office Board, MDPI), and Stefan Tochev (CEO, MDPI) fielding media questions at Prain PR Agency office in Seoul, South Korea.
Over the past three years (2021–2023), we have had some of the most prestigious academic universities ranked among the top 10 Korean institutions publishing with MDPI. Seoul National University had the highest number of publications with MDPI during those three years, publishing nearly 6,000 papers. Universities such as Korea University and Yonsei University also rank among the top 10 Korean institutions publishing with MDPI.
MDPI Hosts Seminar for Academia and Media
As the world’s leading OA publisher, MDPI is actively democratizing science. This is reflected in the seminars we hosted on 21 March to address questions about our editorial processes and ethical standards. The visit garnered media coverage, reflecting our mission to providing high-quality services and fostering open dialogue in the community.

Media coverage generated by our visit to Seoul included the following stories:
“Open access is an unstoppable trend…it will lead the development of the knowledge ecosystem.”
I greatly appreciate the contributions of everyone who took the time to meet with us, share their stories, and hold us accountable for continuing to provide high-quality publishing services while identifying areas for improvement. I am also excited to announce that we have opened an MDPI office in Seoul and will release a press release on MDPI.com, with details, by the end April 2024. The purpose of the office is to establish a local presence to connect with and support the South Korean academic community through institutional partnerships, conferences, author workshops, stakeholder communications, and more.

Inside MDPI
Championing Women’s Healthcare and Access to Healthcare Information
MDPI colleagues from our offices joined in celebrating #IWD2024. In doing so, we emphasized key missions that encompass:
- Empowering women to assume leadership and decision-making roles in both business and science.
- Helping women and girls make informed decisions about their health.
- Recruiting and developing female talent and fostering inclusive workplace environments.
“We are thrilled to recognize the accomplishments of women scientists”
I am proud to see our colleagues enthusiastically supporting the International Women’s Day call to ‘Inspire Inclusion!’ The heart-hands in the collage below symbolize our appreciation of the achievements of women researchers and the recognition of the trailblazers who have courageously made a mark on societies past and present.
We are thrilled to recognize the accomplishments of women scientists through our many MDPI awards and by highlighting success stories. As inspirational figures, female scientists are paving the way for the next generation of women aspiring to pursue careers in engineering, life sciences, computing, and various other STEM fields.
“I consider myself lucky because I work with incredibly talented women who inspire me every day.”
– Dr. Alessandra Pasut, Winner of MDPI's ‘Biology 2023 Young Investigator Award’
“It’s really important to find a supportive and enabling environment in which to do your science; it would have a big impact on you as a person and on your scientific outputs.”
– Dr. Rhea Longley, Winner of the ‘Pathogens 2023 Young Investigator Award’
Open-access publishing, in particular, allows early-career women researchers to share their work more widely, potentially attracting mentorship opportunities and collaborations. This support is crucial for career development and advancement.
Coming Together for Science
MDPI Joins United2Act in Collective Fight to Stop Paper Mills
In my February 2024 CEO Letter, I highlighted some of our recent initiatives aimed at bolstering our commitment to research integrity, including joining the STM Integrity Hub and expanding our Research Integrity and Publication Ethics team (RIPE). Continuing our efforts in coming together for science, I am pleased to share our participation in the United2Act initiative.
The text below is taken from our official announcement:
United2Act represents an international group of stakeholders in the publishing industry committed to addressing the collective challenge posed to research integrity by paper mills.
Scientists and academic publishers have increasingly noted the alarming proliferation of paper mills, recognized as fraudulent entities seeking to manipulate the publication process for financial profit. These entities engage in fraudulent practices such as falsifying or fabricating data, selling co-authorship of fake papers, manipulating peer review, and including inappropriate citations. These actions pose a significant threat to the integrity of the scholarly record, prompting widespread concern among those involved in the academic community.
MDPI has been actively contributing to combat the undermining of the scientific record. Our editors employ a set of tools to detect potential ethical breaches within a manuscript and to tackle the issue of fake papers.
United2Act’s consensus statement is the outcome of a virtual summit held in May 2023. It involved the participation of research bodies, publishers, researchers/sleuths, universities, and publishing infrastructure from 15 countries and resulted in a Consensus Statement outlining five key areas of action for all stakeholders:
- Education and awareness
- Improve post-publication corrections
- Facilitate and organise research on paper mills
- Enable the development of trust markers
- Facilitate dialogue between stakeholders
MDPI is committed to promoting transparency and integrity in scholarly publishing and is continuing to work closely with the scientific community toward this goal.
Closing Thoughts

Visit to Tokyo and Kyoto, Japan
In March, I had the opportunity to visit our Tokyo office and engage with stakeholders in Tokyo and Kyoto. During the visit, I also recorded a video message to welcome Japanese scholars working with MDPI and to highlight our operations in Japan.
We held meetings with Editors-in-Chief, librarians, scholars, and external consultants to gather feedback on our efforts to enhance our reputation and explore additional steps we can take in that direction. Japan's rich cultural heritage, characterized by tradition, respect, and formality, provided valuable insights into meeting the publishing needs specific to Japan.
Japan’s Open Access statistics
Over the years, we have seen a shift from subscription-only to gold OA publishing in Japan, despite the lack of an official mandate. Here are some statistics:
- 2012: 68% of articles were subscription-only, 6% were green Open Access, and 8% were gold Open Access.
- 2016: 55% of articles were subscription-only, 6% were green Open Access, and 20% were gold Open Access.
- 2022: 43% of articles were subscription-only, 7% were green Open Access, and 39% were gold Open Access.
To learn more about the history of OA in Japan as well as about future trends, please read this blog post.
“Japan is the ninth-largest contributor to our total publications”
Left to right: Stefan Tochev (CEO, MDPI), Dr. Izumi Yamamoto (Marketing Manager, MDPI), and Dr. Giulia Stefenelli (Chair of Scientific Office Board, MDPI) visiting Kyoto University in Kyoto, Japan.
MDPI and Japan by Numbers
As at 1 April, over 50,000 MDPI articles have been authored by scholars affiliated with Japanese institutions, making the country the ninth-largest contributor to our total publications. Over the past three years (2020–2023), nearly 90,000 authors affiliated with Japanese institutes have published with MDPI, and we have collaborated with over 4,600 Guest Editors from Japan.
In 2023, we published over 8,200 papers from authors associated with Japanese institutions. MDPI collaborates with 41 institutional partnerships in Japan, including the University of Tokyo, Hokkaido University, and Nagoya University. We have over 2,100 active EBMs from Japan, more than 1,050 EBMs having an H-index between 26 and 50, including 13 serving as Editors-in-Chief.
General Feedback – a side note
A general takeaway from our discussions with stakeholders from around the world is that negative perceptions of MDPI often stem from misinformation, misconceptions, or misunderstandings about MDPI and our practices. While we acknowledge our mistakes and work diligently to address them, maintaining a strong editorial procedure and robust peer-review process, I find that educating stakeholders about our how we do what we do and our ongoing improvements tends to help shift opinions.
That said, we recognize the importance of addressing individual concerns. We take feedback seriously and are continuously working to get better while not compromising the core principles that millions of authors appreciate about MDPI.

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.

We are pleased to announce the expansion of our Research Integrity and Publication Ethics Team (RIPE) at MDPI. The RIPE team has recently welcomed new colleagues, each bringing unique skills and a personal commitment to prioritize ethical considerations in all our work.
The demand for research integrity and high ethical standards in academic publishing is steadily rising across our industry. Our expanded RIPE team will work to enhance and align our practices with industry best practices, ensuring excellence in research integrity and publication ethics.
Stefan Tochev (CEO, MDPI) introduces Dr. Tim Tait-Jamieson (Research Integrity Lead, MDPI) for his presentation on MDPI’s Retraction and Approval Process to a group of Journal Relationship Specialists at the MDPI office in Cluj, Romania: “The demand for research integrity and publication ethics is steadily rising across our industry.”
Introducing our Research Integrity and Publication Ethics Team
Led by Dr. Tim Tait-Jamieson (Research Integrity Lead), the RIPE team comprises Dr. Ivana Resanovic (Research Integrity Manager), Dr. Lavinia Rogojina (Research Integrity Manager), Ms. Diana Apodaritei (Research Integrity Specialist), Dr. Zoltan Mihaly (Research Integrity Specialist), Mr. Aleksandar Đukić (Research Integrity Specialist), Ms. Ana Stankovic (Research Integrity Specialist), and Ms. Anna Pena (Publication Ethics Assistant).
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.

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.

Inside MDPI
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)!
Coming Together for Science
MDPI and TU Delft Adopt Flat Fee Model in Extended Partnership
We are excited to announce a renewed three-year partnership with Delft University of Technology (TU Delft) in the Netherlands. This collaboration introduces a fixed lump-sum fee, covering publishing costs from 2024 to 2026.
“This initiative reflects our dedication to transparent and inclusive publishing”
TU Delft-affiliated authors will enjoy cost-free publishing in any MDPI journal during this period, aligning with our commitment to removing barriers for open access publishing. The agreement supports Plan S compliance and facilitates a seamless publishing process for TU Delft corresponding authors. This initiative reflects our dedication to transparent and inclusive publishing, providing stability and predictability both for authors and for institutions.
For further details on our Institutional Open Access Program (IOAP), please contact us.
Benefits to MDPI’s IOAP
At MDPI we have a long tradition of partnerships, including our Institutional Open Access Program (IOAP). IOAP supports institutions through simplification, access, transparency, APC discounts, and institutional repository deposits. The program simplifies administrative processes, offers central payment, and allows easy opting in and out. Participants gain free access to Susy, MDPI’s online submission system, with extensive article metadata and exportable data. 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.

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.
