MDPI INSIGHTS: The CEO's Letter #30 - Scaling with Integrity, Highly Cited Researchers, KEMÖ Consortium, Michele Parrinello, and Best PhD Thesis Awards
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
With colleagues at MDPI headquarters in Basel, representing the people behind our global growth and shared commitment to integrity.
Scaling with Integrity: A Year of Growth, Responsibility, and Trust
When I look back on 2025, one phrase seems to sum up the year: “Scaling with integrity.” That was our watchword for 2025, and it will remain so as we move forward in to 2026.
Our journal portfolio continued to grow in 2025, reflecting the trust of a widening proportion of the scholarly community.
Today, MDPI has 355 journals indexed in Scopus and 330 in Web of Science – a testimonial to the scale at which our journals meet established external quality criteria. During the year, 45 of our journals were newly accepted into Scopus and 29 into Web of Science (this excludes transferred journals to our portfolio that were already indexed), following rigorous, independent evaluation by the world’s leading indexing bodies
Meeting external quality benchmarks
These results underline the fact that scaling responsibly is not only about expanding our catalogue, but also about meeting external quality benchmarks consistently, transparently, and at scale. Our indexing performance remains one of the strongest independent validations of MDPI’s commitment to rigor, trust, and long-term sustainability.
Over the course of 2025, we made targeted investments to ensure that the integrity of our editorial process scaled to keep pace with our growth. We strengthened our editorial governance by doubling down on our dedicated Publication Ethics department, appointing a Head of Ethics, and expanding our research integrity team by the addition of new specialists plus the creation of embedded editorial ethics roles across key journals. We also introduced new internal ethics guidelines, pre-review integrity checks, and monitoring dashboards to help teams identify potential issues and apply consistent standards across our portfolio.
Besides investing in systems and tools, we of course also invested heavily in our people and culture, delivering organisation-wide training on topics such as image integrity, AI use in publishing, and ethical oversight, while actively engaging with the wider publishing community through COPE and STM forums.
All these efforts reflect a simple principle: growth only matters if it is matched by rigor, responsibility, and trust.
Technology and AI: Supporting the editorial decision-making process
At MDPI, AI is designed to assist, not replace, editorial decision-making. It is one element in a broader system that combines people, technology, and processes to support scale responsibly.
In 2025, we continued to invest heavily in technology that supports quality rather than shortcuts. Our AI team doubled in size, ensuring that increased automation goes hand-in-hand with expertise and oversight. Proprietary AI tools such as Scholar Finder have significantly improved the precision of reviewer matching, while Ethicality has been widely adopted across editorial workflows to identify contextual signals, such as scope alignment and citation behaviour, so that human judgment can be applied where it matters most.
Partnerships: Institutional Open Access Program (IOAP) agreements and Societies
Our recent growth is also reflected in the strength of our partnerships. In 2025, we entered into more than 150 new IOAP agreements, bringing our total to 975 active agreements worldwide. This activity included the signing of our first-ever consortium agreements in North America, renewals of all major national consortia in the UK, Switzerland, Sweden, Norway, Austria, and Croatia, and the conclusion of several flat-fee agreements. At the same time, we concluded a total of 30 agreements, encompassing 24 new Society affiliations, four strategic publishing partnerships, and two journal acquisitions.
In 2025, we opened MDPI USA in Philadelphia – our latest global office, which complements our Toronto office in representing North America. MDPI USA is responsible for accelerating Open Access in the US through ongoing support of our scholars and for expanding our institutional and society partnerships.
On the other side of the globe, meanwhile, we signed an IOAP agreement in India, allowing researchers discounted Article Processing Charges (APCs), streamlined APC management for universities, and visibility into submissions, supporting India’s push for wider Open Access by offering flexible models and helping institutions meet national mandates such as Plan S.
Sustainability, sponsorships and awards
We continued to expand our sustainability efforts during 2025, hosting the 11th World Sustainability Forum, awarding CHF 125,000 in sustainability-related funding, and launching the Z-Forum on Sustainability and Innovation conference, which will officially take place in January 2026.
We also saw a record year for conference sponsorships and awards (while establishing new awards such as the Michele Parrinello Award), recognising scholars across disciplines and reinforcing our commitment to supporting the global research community at every stage of the academic journey.
Deepening our relationships
In 2025, I had the opportunity to travel more widely than ever before on MDPI business, meeting many of our stakeholders face to face and relishing the opportunity to gain a deeper understanding of their science communication needs. It was also excellent to visit a large number of MDPI offices and witness the commitment and service orientation of so many of our colleagues around the world. I shall resume my itinerary in the new year, and I look forward to many more such interactions.
Looking ahead to 2026, we will be celebrating a very significant milestone: 30 years of MDPI. From our foundation as a single Open Access journal in 1996 to the global publishing organisation we are today, our mission has remained consistent: advancing Open Access through rigorous and trustworthy scientific communication.
I would like to take this opportunity to thank all our stakeholders – authors, Editors-in-Chief, Editorial Board members, and reviewers – who have placed their trust in us during 2025. On behalf of the entire MDPI team, I look forward to deepening our relationships yet further in 2026 and celebrating 30 Years of Open Science at MDPI, something we’ve built together.
Basel, Switzerland, where MDPI was founded in 1996.
Impactful Research
621 MDPI Editors Named Highly Cited Researchers in 2025
I am pleased to share an important milestone for our editorial community and for MDPI. In late November, Clarivate announced the 2025 Highly Cited Researchers, and 621 MDPI Editorial Board Members were included among the most influential scientific contributors over the past decade!
The 621 editors come from 33 countries, representing 21 scientific disciplines, and account for nearly one in every ten Highly Cited Researchers globally. This recognition speaks to the depth of expertise across our Editorial Boards and the strength of the scientific communities that choose to collaborate with MDPI. It is important to note that while citation metrics are not in themselves a proxy for quality, they do offer one lens on sustained scientific influence.
“Our strength comes from the scientific communities who choose to work with us”
Why this is important
Having more than 600 editors recognized on this list highlights:
- The high level of expertise guiding peer review across our journals
- The global and disciplinary diversity within our Editorial Boards
- Our commitment to maintaining strong, knowledgeable, and engaged editorial oversight
Impactful science is of course shaped by broad, diverse research communities, and no single metric captures the full picture of research quality. However, this recognition does serve as meaningful, independent affirmation of the calibre of many editors who contribute to MDPI’s work.
A closer look at the recognition
Clarivate’s methodology highlights researchers whose publications rank in the top one per cent by citation count, reflecting consistent influence over the past decade. The process includes:
- Evaluation of c. 200,000 highly cited papers
- Removal of retracted publications
- Filtering of papers with unusually large authorship groups to focus on clear contributions
That so many of our editors meet these thresholds reflects the impact of the communities behind our journals.
What this means going forward
This recognition underlines the fact that our strength comes from the scientific communities who choose to work with us.
For authors, partners, and readers, it confirms that:
- MDPI journals benefit from editorial guidance grounded in active, high-impact research
- Our Editorial boards include leaders who are helping shape the future direction of their fields
- MDPI continues to attract experts who value openness, efficiency, and scientific integrity
For our internal teams, it is a reminder that the work we do every day (supporting editors, refining workflows, and improving systems) directly contributes to the trust placed in MDPI by researchers worldwide.
Thank you to all our editorial teams, publishing staff, and journal relationship specialists, and to everyone who collaborates with our Editorial Boards. Achievements like this are only possible because of your ongoing hard work, dedication, and collaboration.

Inside MDPI
MDPI Launches the Michele Parrinello Award for Computational Physical Science
In case you missed it, in November, we announced the launch of the Michele Parrinello Award. This new biennial international award will recognize pioneering contributions in computational physical science. The award honours Michele Parrinello, one of the most influential scientists of the past half-century in atomistic simulations and computational materials research.
This award reflects MDPI’s long-standing commitment to recognizing scientific excellence, supporting foundational research, and inspiring the next generation of scholars across disciplines.
“Be confident that what you do is meaningful”
Honouring a transformative scientific legacy
Professor Parrinello’s work has fundamentally reshaped how scientists model matter at the atomic scale. Together with Roberto Car, he introduced ab initio molecular dynamics, widely known as the Car–Parrinello method, opening new pathways in electronic structure calculations and molecular simulations. His subsequent contributions, including the Parrinello–Rahman method and metadynamics, have become core tools across physics, chemistry, materials science, and increasingly biology.
“Do not be afraid of new things. I see it many times when we discuss a new thing that young people are scared to go against the mainstream a little bit, thinking, ‘What is going to happen to me?’ and so on. Be confident that what you do is meaningful, and do not be afraid, do not listen too much to what other people have to say.”
– Professor Michele Parrinello
A global, community-led award
The award committee is chaired by Xin-Gao Gong, Professor of Physics at Fudan University and academician of the Chinese Academy of Sciences.
The Institute for Computational Physical Sciences at Fudan University will serve as the supporting institute, reinforcing the award’s international and cross-cultural foundation.
Nominations for the first edition of the Michele Parrinello Award opened on 1 November 2025, with submissions accepted until March 2026. The award will recognize scientists whose work has advanced computational physical science across physics, chemistry, and materials research – fields increasingly central to energy, sustainability, advanced manufacturing, and technological innovation.
Why this matters for MDPI
The Michele Parrinello Award is part of the MDPI Sustainability Foundation, which supports science as a driver of long-term societal progress.
Alongside other foundation-level honours, including the World Sustainability Award, the Emerging Sustainability Leader Award, and the Tu Youyou Award, this new prize builds on our role in supporting excellence across career stages and disciplines.
MDPI journals and programs continue to recognize researchers through Best Paper Awards, Young Investigator Awards, Travel Awards, Best PhD Thesis Awards, and Outstanding Reviewer Awards. Together, these initiatives reflect a simple belief: strong scientific communities are built through recognition, trust, and sustained support.
As MDPI approaches its 30th anniversary, the launch of the Michele Parrinello Award highlights our commitment not only to publishing research but also to helping shape the future of science by celebrating those who expand its boundaries.
Coming Together for Science
KEMÖ Consortium (Austria) Extends Open Access Agreement with MDPI until 2027

MDPI INSIGHTS: The CEO's Letter #28 - WSF11, Nobel Laureates, Proofig AI, Romania Summit, STM and FBF
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
Highlights from the 11th World Sustainability Forum in Barcelona
I’m pleased to share some highlights from the 11th World Sustainability Forum (WSF 11), held in Barcelona on 2–3 October 2025 under the theme Sustainable and Resilient Cities.
Why WSF matters
The WSF series is a flagship initiative for MDPI and is supported by the MDPI Sustainability Foundation. It serves as a transdisciplinary platform for researchers, policymakers, and stakeholders to engage on sustainability challenges. WSF is now held annually as part of our commitment to maintain momentum in the sustainability discourse.

This year’s Barcelona edition focused on urban resilience, landscape design, and social community impact in the sustainability space. Over 48 hours of sessions, we brought together leading minds across disciplines to translate vision into practice. With participants from 53 countries across all continents, WSF 11 was truly global in scope.
“WSF is now held annually as part of our commitment to maintain momentum in the sustainability discourse”
What made WSF 11 especially successful (from my vantage point) was the level of positive engagement with our participants. Chief editors, researchers, and attendees repeatedly told me how professionally executed the event was, highlighting the high energy, logistical smoothness and quality of MDPI’s event management. That kind of recognition from peers really builds our reputation as more than just a publisher, but as a convener of meaningful scientific dialogue.
Our conferences are a form of experiential marketing as they create memorable and immersive connections between a brand and attendees. These positive associations build promotion and brand loyalty, ultimately impacting the MDPI’s trust and reputation for the better.
WSF 11: By the numbers
Here’s a quick snapshot of WSF 11’s scale and reach:
- 181 registrations across global participants.
- 8 keynote speakers and 5 invited speakers.
- 144 abstracts accepted (over 355 submitted), resulting in 75 short talks and 69 posters.
- 53 countries were represented across all continents, making it a truly international event.
- First time that we ran parallel sessions for WSF (an ambitious program).
- A dedicated awards ceremony to honour outstanding sustainability research: World Sustainability Award (WSA) x 2 winners, and Emerging Sustainability Leader Award (ESLA) x 3 winners.
Interviews with our World Sustainability Award Winners
One of the most rewarding parts of WSF is recognizing researchers whose work advances sustainability in powerful ways. In our Blog series, Daniella Maritan-Thomson (Content Specialist, MDPI) interviewed the two winners of the World Sustainability Award, Professor Dr. Stuart Pimm and Dr. Abdelbagi M. Ismail, who offered insights to the human side of sustainability research, the people behind the data, and the stories behind the science.

We also recognized three recipients of the Emerging Sustainability Leader Award: Prof. Dr. Vhahangwele Masindi, Dr. Katya Rhodes, and Prof. Dr. Myriam Ertz, for their contributions as early-career researchers advancing sustainability through innovation, impact, and academic excellence across the field.
What this means for MDPI
- Building our global identity in events
WSF is a marquee MDPI event, not just a gathering, but a statement of how we wish to position ourselves in the global sustainability ecosystem. The positive feedback helps us build on our approach for future editions, so that we remain a reference point for quality, relevance, and engagement. - Expanding capacity across offices
The success of WSF 11 in Barcelona’s would not have happened without great teamwork from Basel, Barcelona, Romania, the UK, and the APAC Conference team. Thanks to everyone for their work to bring this ambitious event to life. - Supporting MDPI’s mission
At this event, I had the opportunity to present on MDPI's role in Open Access, sustainability publishing, and the intersection of science and policy. WSF is not only about the science; it’s also a platform for us to position MDPI as a thought leader and a collaborator in shaping the future of sustainable research.
I look forward to the WSF momentum as we work towards WSF 12 in Hong Kong, which is scheduled for August 2026.

Inside MDPI
Strengthening Research Integrity: MDPI partners with Proofig AI
I’m pleased to share that MDPI has entered a multi-year partnership with Proofig AI, a leader in AI-driven proofing and integrity software for scientific publishing. This follows the success of our pilot program, in which Proofig AI proved highly effective in detecting duplicated, altered, and manipulated images across biomedical submissions.
Safeguarding the credibility of the research we publish
Research integrity is at the core of MDPI’s mission. The life sciences, in particular, face increasing risks of image-related issues due to advanced editing tools and generative AI. By integrating Proofig AI into our workflows, we improve our ability to detect issues early, reduce post-publication corrections, and safeguard the credibility of the research we publish.
Pilot outcomes
- Successful detection of duplicated confocal and histology images, even when altered to disguise similarities.
- Early results showed a significant drop in post-publication image manipulation flags year-on-year.
- Positive feedback from editors and staff highlighted the tool’s ease of use and reliability.
Dr. Dror Kolodkin-Gal (co-founder and CEO of Proofig AI) said:
“The MDPI team conducted a highly professional and carefully monitored pilot, achieving excellent results in detecting problematic images.
Their fast and effective integration process was impressive, and we are excited to contribute to this important collaboration.”
Sanita Meijere (IT Product and Project Manager, MDPI), shared:
“For more than a year, we’ve tested all the available image manipulation detection tools. Proofig AI’s quality and ease of use, alongside positive feedback from our internal users, made their software a clear stand-out.
We’re thrilled to be moving forward with this partnership, ensuring we do our utmost to protect MDPI’s biomedical journals. Using this advanced image proofing software reaffirms MDPI’s commitment to maintaining the highest standards in research integrity.”
Raising the bar for integrity
This partnership sets a new benchmark for quality control in biomedical publishing.
As Tim Tait-Jamieson (Head of Publication Ethics, MDPI), explains:
“The life sciences are disproportionately affected by research integrity issues, making vigilance in this field especially critical. This is driven, in part, by the increasing sophistication of image editing software and generative AI.
Whether accidental or deliberate, image manipulation can have a lasting impact on credibility. By integrating Proofig AI into our editorial workflows, we strengthen our ability to detect scientific misconduct early and reduce post-publication amendments.”
Faster and more accurate quality control
Proofig will automatically flag potentially problematic images during submission checks, giving our editors more confidence in the integrity of manuscripts and freeing up time to focus on editorial decisions. The tool will also reduce the burden of manual checks, while supporting faster and more accurate quality control. This partnership reinforces MDPI's reputation as a publisher that takes integrity seriously and continues to invest in tools to support authors, editors, and reviewers alike.
A big thank-you to all colleagues who supported the pilot and rollout. You can read more in our MDPI Blog post.
Coming Together for Science
The MDPI Romania Summit 2025
On 21–22 October, I had the pleasure of joining our colleagues in Bucharest for the MDPI Romania Summit 2025. The event was organized by our Romania Marketing team, with support from colleagues across our Romanian offices. It brought together academics, policymakers, and collaborators to discuss the country’s evolving research landscape.

Closing Thoughts
STM and FBF 2025: Connecting Through Science and Publishing
Stefan Tochev (CEO, MDPI), Constanze Schelhorn (Head of Indexing, MDPI) at STM Conference, Frankfurt, 14 October 2025.
On 13–14 October, I attended the STM Frankfurt Conference 2025, my fourth visit to the Frankfurt event, and it continues to be one of the most valuable gatherings in our industry.
The STM meeting brings together the publishing community and key opinion leaders to speak on current trends and challenges shaping our industry.
This year’s theme – “Science Diplomacy: What is it and How Does it Work?” – unpacked the growing intersection of science, policy, and publishing.
Discussion topics ranged from what is science diplomacy and how publishers can contribute to global collaboration to how science communication can help maintain trust during an era of disruption.
I was joined by Dr. Constanze Schelhorn, our Head of Indexing, who met with representatives from Scopus, Web of Science, Digital Science, ProQuest, and other partners. These meetings give us a chance to share feedback on our collaborations, learn about new updates being developed, and build our relationships with indexing bodies.
“The STM meeting brings together the publishing community and key opinion leaders”
STM also provides a space to connect with industry peers, as I did with colleagues from Elsevier, Frontiers, Clarivate, Sage, and STM itself, reinforcing MDPI’s engagement within the broader publishing community. It was also nice to bump into some former colleagues and see them continuing to grow in their publishing careers.
At the Frankfurt Book Fair
The MDPI booth at the 2025 Frankfurt Book Fair.
Following STM, I spent the next day at the Frankfurt Book Fair (15–19 October) – one of the largest and most influential events in the publishing world.
It’s always inspiring to see the scale and energy of this global gathering, which spans everything from books and education to digital innovation and academic publishing.
We set up an MDPI booth to host discussions with partners, vendors, and researchers.
The Fair ran into the weekend, with colleagues from several MDPI departments attending to represent the company and connect with the scholarly community.
Events like STM and FBF are a nice reminder of how dynamic and interconnected our industry is, and how important it is for MDPI to continue taking part in global conversations about science, communication, and the future of publishing.

MDPI INSIGHTS: The CEO's Letter #27 - OASPA 2025, COUNTER 5.1, UK Summit in London, MDPI at the Italian Senate
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 at OASPA 2025: Embracing the Complexity of Open Access
From 22 to 24 September, I joined the OASPA 2025 Annual Conference in Leuven, Belgium, where the theme, “Embracing the Complexity – How do we get to 100% Open Access?” tackled the hard questions about the future of scholarly communication.
With MDPI a longstanding member of the Open Access Scholarly Publishing Association (OASPA) and Platinum sponsor of the conference, I was invited to present and participate in important discussions on how we can continue to move the needle in Open Access (OA) publishing.
From 50% to 100% Open Access
Last year’s OASPA conference celebrated a major milestone – reaching 50% of global research outputs published as OA. But, as noted during the conference, this was the “easy” part. The challenge ahead is much tougher: how do we take OA from 50% to 100%? For many academics and institutions, OA is still relatively new, and thus it is essential for us to continue educating people as to what OA is, how it works, and why it matters.
Stefan Tochev (CEO, MDPI) presenting at OASPA’s 2025 Annual Conference in Leuven, Belgium.
MDPI’s perspective
At MDPI, we are fully committed to this. As a 100% OA publisher, our growth is inseparable from the success of OA itself. In many ways, MDPI is a byproduct of the global adoption of OA, and we play an important role in helping to advance it further.
I had the opportunity to share MDPI’s perspective in the panel discussion entitled: "Hello from the other side: views from fully Open Access journals using APCs," alongside industry colleagues from PLOS, eLife, AOSIS, and Frontiers.
Instead of giving a standard presentation, I highlighted aspects of MDPI that the audience might not be aware of. I also presented on the opportunities and challenges facing publishers that are already fully OA, the importance of diverse models in achieving 100% OA, and why OA is the baseline while Open Science is the future.
Recognizing Gold OA
As part of the panel, I had undertaken to make some bold and provocative statements. I therefore emphasized a point that is sometimes overlooked: we didn’t reach 50% OA without Gold OA – it accounts for more than half of all OA publications today. And we certainly won’t reach 100% OA without it.
“By educating the community and working together, we can continue to take Open Science to the next level”
“When people speak about Gold OA and MDPI, they should ‘put some respek on our name.”
MDPI is a leader in Gold OA and has been a driver of this progress at scale.
While Gold OA and MDPI are sometimes slighted, both deserve recognition for their contributions to advancing Open Science globally.
I closed my presentation with a reminder that the good we do is sometimes overlooked, and that when people speak about Gold OA and MDPI, they should "put some respek on our name."
I’m pleased to have seen attendees sharing positive experiences with MDPI, reminding us that we bring real value to the OA movement and deserve a stronger reputation. We also engaged in constructive conversations about various topics, including cost transparency.
A few themes that I took away from the conference:
- Quality and integrity matter as much as access. OA publishers must not lose sight of research integrity, inclusivity, and sustainability while pursuing 100% OA.
- Global collaboration is essential. Policies, funding models, and infrastructure differ around the world, and we will need cross-border collaboration to make OA a truly global reality.
- Open Science is the bigger story. OA is just the first step – the future lies in open data, open peer review, research reproducibility, etc.
“MDPI’s scale allows us to better support authors, reinvest in communities, and push Open Science forward”
How we communicate MDPI’s role
For us at MDPI, this is also a reminder of how we communicate externally. When we tell our story, we shouldn’t forget to start with the bigger picture – Open Science and Open Access. Then we connect it to MDPI, our journals, services, and initiatives, exemplifying the fact that we are part of a mission larger than ourselves.
MDPI colleagues Clàudia Aunós (Society Partnerships), Marta Colomer (External Affairs), Stefan Tochev (CEO), and Nikola Paunovic (Scilit), at OASPA’s 2025 Annual Conference in Leuven, Belgium.
The journey to 100% OA will not be simple. But by educating the community and working together, we can continue to take Open Science to the next level.
Impactful Research
MDPI becomes COUNTER 5.1 compliant across 480+ Journals
I’m pleased to share that MDPI has officially become COUNTER 5.1 compliant and has joined the COUNTER Registry.
For those who might not be familiar with it, COUNTER provides international standards for tracking and reporting how research is being used. By becoming COUNTER 5.1 compliant, MDPI can now deliver credible, comparable, and transparent usage reports across our entire journal portfolio.
“MDPI is showing that they want to be measured against the same yardstick as other publishers”
Why is this important?
Because usage statistics aren’t just numbers: they’re powerful tools that help our authors, institutions, and consortia understand the real impact of their research. With COUNTER compliant reports, our institutional partners can now make more informed decisions about publishing agreements, funding allocations, and the long-term value of Open Access.
In practical terms, MDPI will now provide Platform, Title, and Item Reports, with standardized usage views available at the institute and consortium level. These reports cover usage from January 2024 onwards and will be updated monthly. Institutions will be able to access them via SuSy, or automatically through the COUNTER API.
I’d like to highlight and thank Becky Castellon, our Institutional Partnerships Manager, who has played a key role in driving this project forward. Becky captured it perfectly when she said: "Through these usage reports, our global research community can access trustworthy data about how their work is being used and accessed
This information is often vital for reviewing publishing partnership agreements and for making informed decisions about future funding allocations."
We also received encouraging feedback from Tasha Mellins-Cohen, Executive Director at COUNTER Metrics:
"We’re delighted to see born-OA publishers engaging with COUNTER. Our normalised usage metrics are relied on as the basis for credible return-on-investment calculations by libraries worldwide. By adopting the COUNTER standard, MDPI is showing that they want to be measured against the same yardstick as other publishers."
For MDPI, this milestone is another step in our commitment to transparency, trust, and impact. By adopting COUNTER’s standards, we’re not just aligning with best practice; we’re ensuring that Open Access publishing is measured on the same terms as traditional publishing, proving its value in concrete and globally recognized ways.
This is an important milestone for MDPI, but more importantly for the researchers, librarians, and institutions we serve. Transparency builds trust, and COUNTER compliance helps us show the global reach and influence of Open Access publishing in the clearest way possible.
Inside Research

Welcoming Prof. Lee (EiC of AI Sensors) to Basel
On 11 September, we welcomed Prof. Dr. Chengkuo Lee, Editor-in-Chief of our new journal AI Sensors, to our Basel office. Prof. Lee is a high profiled researcher (h-index 104, 37,000+ citations), a longtime collaborator with MDPI (25 published articles), and has already chaired several AI Sensors (AIS)-related conferences with us, including the recent event in Kuala Lumpur, where AI Sensors held its first editorial board meeting.

Every journal has a story
During his visit, we exchanged ideas on how to build the journal’s identity and impact. A key takeaway that I shared was that every journal has a story: its vision, its purpose, and the community it brings together.
That story is what connects with readers and authors, beyond metrics alone.
I encouraged everyone working on journals to reflect: What is the story of your journal? And how can you bring that story to the forefront in how you communicate about it?
How MDPI supports new journals
Constanze Schelhorn (Head of Indexing, MDPI) presenting on the MDPI indexing process at the company’s headquarters in Basel.
We also shared with Prof. Lee how MDPI supports journals through our Institutional Open Access Program, indexing expertise, and the work of our Journal Relationship Specialists.
Launching a new journal is ambitious, but with our strong track record (93% Scopus and 87% Web of Science acceptance rates in 2024), Prof. Lee felt confident that AI Sensors will find its place in the scholarly landscape.
Having spent some hours together, it’s clear that Prof. Lee is not only an Editor-in-Chief but also an ambassador for MDPI. His leadership and collaboration reflect the mission MDPI by which MDPI lives: accelerating Open Access and advancing Open Science.
Special thanks to Constanze Schelhorn (Head of Indexing), Ting Leng (JRS, Managing Editor, AI Sensors), Lin Li (Publisher, AI Sensors), Aimar Xiong (Publisher), and Christian Eberhard (Office Administrator, Basel), for organizing and hosting the meeting.
Coming Together for Science
Highlights from the MDPI UK Summit in London
I was pleased to be back in the UK in September, supporting our Manchester team in hosting their first MDPI Summit in London. This day-and-a-half private event brought together 25 Chief Editors and Associate Editors to exchange knowledge, learn about latest developments at MDPI, and engage in discussions on advancing Open Science. The program included MDPI and guest presentations, and Q&A sessions.
Why these summits matter
Our Summits provide a platform to:
- Share updates on the latest developments at MDPI, our editorial processes, research integrity practices, and indexing.
- Highlight collaborations with institutions and societies in the region.
- Offer external perspectives from guest speakers.
- Create space for Chief Editors to share their insights, ask questions, network, and help shape MDPI’s path forward.
These gatherings are more than updates: they improve our relationships with Chief Editors, who serve not only as leaders of their journals but also as ambassadors for MDPI within the research community. We often hear that this type of event is unique, something many other publishers do not provide. It shows that we care and are willing to go the extra mile to recognize and engage our key collaborators.

MDPI at the Italian Senate: Promoting Environmental Medicine and Open Science
On 16 September, Dr. Giulia Stefenelli (Scientific Communications Lead) and I had the honour of participating in a press conference at the Italian Senate in Rome, organized by the Italian Society of Environmental Medicine (SIMA) to promote the upcoming 2nd International Conference on Environmental Medicine (ICEM) (20–21 November 2025).
This is an important event for MDPI, as we are the exclusive publishing partner for ICEM and have recently launched a new journal with SIMA, further building our presence both in Italy and within this important field of research.
Why this matters
- The promotion of ICEM has received extensive national media coverage (more than 15 mentions in major Italian outlets; see links below).
- The press conference brought together leading policymakers, academics, and Nobel Laureates to emphasize the impact of environmental exposures and epigenetics on human health.
- We were introduced to government ministries, university rectors, and influential stakeholders, which helps us bolster MDPI’s visibility and reputation in Italy.
Highlights
Nobel Laureate Sir Richard Roberts joined the discussion, underlining the importance of environmental medicine in shaping future health outcomes. Nobel Laureate Prof. Dr. Tong Zhu (Peking University) will also speak at the November conference.
Institutional representatives included the Italian Minister of the Environment and Energy Security, the Italian Undersecretary for Health, and senior officials from the World Health Organization.
In my closing remarks, I highlighted that:
“Over the past five years, about 65% of research published in Italy has been Open Access, compared to an average of 55% worldwide.”
Italian research ranked seventh among the top 20 countries in average citations during this period, reflecting its strong international influence. Not only is Italy producing a high volume of research; it is also producing research of outstanding quality.
MDPI’s role
This event was not only about promoting ICEM but also about showcasing MDPI’s commitment to Open Access and our ability to connect scientific publishing with leading academic, medical, and policy institutions.
As Giulia Stefenelli noted:
“This event was highly relevant for MDPI, as it not only showcased our strong commitment to OA but also emphasized our role in advancing important fields such as Environmental Medicine.”
