Richard DiMarchi and Rolf Müller Share the 2024 Tu Youyou Award

We are pleased to announce that the 2024 Tu Youyou Award has been conferred upon Richard DiMarchi and Rolf Müller, in recognition of their significant contributions to natural products chemistry and medicinal chemistry.
![]() Richard DiMarchi Indiana University, USA |
Prof. Richard DiMarchi is a Distinguished Professor of Chemistry and Gill Chair in Biomolecular Sciences at Indiana University, USA. He is a member of the National Academy of Medicine and the National Inventors Hall of Fame. Dr. DiMarchi is a former Group Vice President at Eli Lilly and later at Novo Nordisk. He is recognized for his contributions to the discovery and development of rDNA-derived Humulin®, Humalog®, rGlucagon®, and Forteo®. His academic research has broadened the understanding of glucagon and incretin physiology and pioneered the discovery of single-molecule multi-mechanism agonists for the treatment of diabetes and obesity. The central element to success has been the chemical vision and technology to install within single molecules simultaneous agonism at related G-protein coupled receptors, coupled to the counter-intuitive discovery that glucagon and GIP agonism could synergize the therapeutic efficacy of GLP-1. These peptides and their conceptual approach have transformed the management of excessive body weight to a condition comparable to how hypertension, adult-onset diabetes, and excess cholesterol are medicinally managed. |
“Professor DiMarchi was recognized by the 2024 Tu Youyou Award Committee members as being an exceptional leader in the medicinal chemistry of peptides and proteins of natural origin, and as a pioneer in the field of chemical biotechnology. His very important discoveries have led to breakthroughs in new drugs related to the therapy of diabetes and obesity. He has been named as an inventor on a very large number of patents, and he has had initially a highly successful scientific and administrative career in industry, which was followed by over two decades in academia as a distinguished professor.” —Prof. Dr. A. Douglas Kinghorn, Chair of the Award Committee |

MDPI INSIGHTS: The CEO's Letter #24 - 2024 Impact Factor & CiteScore, MDPI Summits France & USA, Tu Youyou Award

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’s 2024 Impact Factor Highlights
For those of our readers who are new to academic publishing, you may have heard some news in June around the Impact Factor release. Every year, typically in June, Clarivate releases its annual Journal Citation Reports (JCR), which include Journal Impact Factors (JIF). This metric is widely used in academic publishing to reflect the average number of citations received by recent articles in each journal.
While Impact Factor is just one of many indicators of journal influence, it remains a major milestone for authors, editors, and publishers. It’s used to assess journal visibility, researcher recognition, and scholarly reach. Throughout our international meetings and events, it’s clear that the Impact Factor is something many of our authors and editorial board members care about, as it can influence where they choose to submit an article and the funding they receive for their research.
“These results reflect the trust that the scholarly community places in MDPI”
MDPI’s 2024 Impact Factor Highlights
- 298 MDPI journals received a Journal Impact Factor.
- 60 journals earned their first-ever Impact Factor
- To put this in perspective: MDPI’s 60 new journal acceptances into the Web of Science was the second highest number of any publisher in 2024, behind Elsevier and ahead of Springer Nature. Our 87% acceptance rate for journals submitted to Web of Science shows the strength of our editorial process and our proven ability to develop journals aligned with Clarivate’s 24 evaluation criteria.
- Notably, Textiles, Mathematics, International Journal of Neonatal Screening, Smart Cities, Systems, and Pharmaceutics ranked in the top 10% in their respective categories, highlighting their growing influence and prestige within their academic fields. This shows that high-quality indexing goes beyond visibility; it upholds credibility and trust.
- 193 MDPI journals are now ranked in the top 50% (Q1/Q2) of their subject categories.
- What does this mean, and why is it important? Journals are ranked by quartiles within their field, based on their Impact Factor. Q1 represents the top 25% of journals in their category, Q2 the next 25%, and so on. Being in Q1 or Q2 shows that a journal is performing well relative to other journals in its category. Authors and institutions often look at quartile rankings when choosing where to publish – it’s an important indicator of visibility and recognition, within its respective category.
- 116 of our previously ranked journals increased their Impact Factor.
- 14 MDPI journals achieved an Impact Factor of 5.0 or higher, suggesting a high degree of influence and visibility.
These results reflect our staff's hard work: from our editorial and production teams to our indexing, communications, and data teams, and beyond. This also reflects the trust that the scholarly community places in MDPI, reinforcing the message that when researchers publish with MDPI, they publish with impact.
Open Access with Impact
As the leading fully open access publisher, our journals have received a total of 18.4 million citations in the Web of Science by the end of 2024, reflecting the growing reach and engagement of research published with MDPI. We are committed to making scientific research freely accessible to everyone, everywhere. With the support of more than 4.2 million contributing authors, we’re proud to support the global shift toward open access.
Further Reading
If you’d like to better understand how journals get indexed and why Impact Factors matter, please read this recent interview with Dr. Constanze Schelhorn (Head of Indexing). It gives you a behind-the-scenes look at the role our indexing team plays in supporting journal indexing and visibility.
You can also read our official news announcement shared last week: MDPI Journals in the 2024 Journal Citation Reports.
Thank you to everyone, from our authors and reviewers to our editors and internal teams, who contributed to the progress of our journal indexing in 2024. We’re continuing to build journals that are recognized and trusted across disciplines.
Impactful Research
MDPI Journals See Continued Growth in 2024 CiteScore Results
Continuing our indexing updates, I’m pleased to share that MDPI has achieved strong results in the latest CiteScore metrics, released on 5 June by Scopus. These results reflect the collective efforts of our editors, reviewers, authors, and internal teams, with their dedication to quality and visibility in scientific publishing. You can read the full announcement here.
2024 Highlights:
- 322 MDPI journals received a CiteScore (up from 274 last year).
- 283 journals (88%) are ranked in Q1 or Q2 of their subject categories.
- 237 journals (85%) saw an increase in their CiteScore compared to last year.
- 48 journals received a CiteScore for the first time.
- 39 journals are now placed in the top 10% of their subject areas.
“This growth highlights our commitment to supporting open, trusted science”
What is CiteScore and how is it measured?
CiteScore metrics are developed by Elsevier as an alternative to the Impact Factor. They measure the citation impact of journals and can be accessed freely on Scopus. The metric represents the yearly average number of citations to recent articles published in a journal. If you’re interested in learning more about citation metrics and how we use them, check out this blog post.
Why is this important?
These results show the growing recognition for, and impact of, MDPI journals across disciplines. CiteScore rankings help researchers, institutions, and funders assess where high-quality work is being published. This growth improves our journals’ positioning in the publishing landscape and highlights our commitment to supporting open, trusted science.
Inside MDPI
Highlights from the MDPI USA Summit in Boston (5–6 June)
With several Summits already behind us, I think this is a good time to reflect on the purpose of these Summits.
Why do we organize MDPI Summits?
These one-and-a-half-day, invite-only gatherings are designed to improve our relationships with Chief Editors who lead our journals and are respected voices in their fields. The Summits aim to:
- Share MDPI’s values, achievements, editorial practices, and local market collaborations.
- Collect feedback on MDPI operations and journal practices.
- Empower Chief Editors to confidently represent MDPI beyond the Summit.
While Chief Editors know their journals well, these events help them better understand MDPI. We want them to be ambassadors for our brand. The aim is for them to walk away informed, engaged, and equipped to share positively about MDPI.

Coming Together for Science
Highlights from the MDPI France Summit in Paris (12–13 June)
We completed our first MDPI France Summit in Paris last week, and it was a special event. Attendees were engaged from beginning to end, remaining after hours to network and collaborate.
|
|
|
Why a France Summit?
We chose to host a France Summit in view of the recent challenges MDPI has faced with the National Centre for Scientific Research (CNRS). What we took away from the event is that our authors and editors very much appreciate and enjoy working with us, but we need to address the concerns raised by CNRS, around Article Processing Charges (APCs) and the funding of gold open access publications.
“Our authors and editors very much enjoy working with us”
Some of the claims made in the June 2023 interview with Alain Schuhl, the Deputy CEO for Science at the CNRS, are simply not factual. For example, they state that MDPI’s “average APC charges per article are now around the same as Springer Nature’s.” Here is the relevant passage, reproduced verbatim:
This is not accurate.
A recent preprint analysing APC data from Elsevier, Springer Nature, Wiley, PLOS, MDPI, and Frontiers (2019–2023) shows that MDPI’s average APCs remain significantly lower than those of Springer Nature and several other major publishers.
The MDPI Summits are part of our outreach and communication efforts to address misconceptions and clarify MDPI’s position as one of the most accessible and affordable major gold open access publishers in the world.
Summit Overview
Held on 12–13 June, the France Summit gathered over 20 Chief Editors to learn more about MDPI’s activities and collaborations in France. Many of these editors are influential in their institutions and professional societies. Several also have connections to CNRS, which makes this an important opportunity to clarify how we operate and build trust through open and transparent communication and hopefully turn our editors into informed advocates of MDPI.
Summit Feedback
The feedback has been very positive, with most attendees completing the post-event survey and all rating the experience as Excellent or Good. A few highlights:
- “The whole thing was highly professional and, above all, provided quantified details that will allow us to better answer questions surrounding MDPI.”
- “The summit was an opportunity to meet personally various people directly engaged in the organization and policies of MDPI, which made it possible to clarify some important points concerning publishing with MDPI.”
- “Very well organized! A great opportunity to see all French MDPI partners and editors.”
Program Highlights:
Moderated by Miruna Adelina Nicolcioiu (Senior Conference Producer), the program featured:
- MDPI Overview and France Collaboration – Stefan Tochev (CEO)
- MDPI Editorial Process and Peer-Review Quality – Dr. Marta Colomer (Public Affairs Specialist)
- Institutional Partnerships and Open Access Funding Models – Becky Castellon (Institutional Partnerships Manager)
- AI in Publishing and MDPI's Actions – Daniele Raimondi (Data Scientist)
- Publication Ethics: Global Trends – Diana Cristina Apodaritei (Research Integrity Specialist)

World Environment Day—“Beat Plastic Pollution”, 5 June 2025

World Environment Day is an urgent call to action as nature suffers from the devastating impacts of human activity. Annual plastic production exceeds 400 million tons, half of which is single-use plastic, with under 10% recycled. 11 million tons of plastic (equal to 2,200 Eiffel Towers) pollute waterways yearly. Microplastics contaminate our food, water, and air, with humans ingesting over 50,000 particles annually. This pollution harms health and ecosystems globally. A solution does exist, however. Governments, businesses, and individuals must adhere to the 5Rs—Refuse, Reduce, Reuse, Recycle, and Rethink. Join #BeatPlasticPollution this World Environment Day to create a sustainable future.
On this significant day, we are proud to present a curated collection of articles and initiatives dedicated to groundbreaking research and innovative solutions for protecting the environment and beating plastic pollution. We invite readers to explore these resources and join us in our shared mission of a sustainable vision of the future. Together, we can pave the way for a cleaner, healthier planet.

In May we hosted the MDPI Spain Summit in Barcelona – our second summit in the city following the inaugural one in November 2023.
Stefan Tochev (CEO, MDPI) at the MDPI Spain Summit in Barcelona, 22 May 2025.
Creating a space for exchange of views
The goal of our summits is to bring together Chief Editors of MDPI journals from across disciplines and institutions. These intimate gatherings provide a platform to present the latest developments at MDPI and to initiate open conversations about our journals, the future of open access, and the evolving landscape of scientific publishing.
Most importantly, these are opportunities for in-person connection, providing a more meaningful space for the exchange of views and for building long-term relationships.
Exploring the future of scientific publishing in Spain
The summit took place on 21–22 May and featured a mix of MDPI presentations (including two guest presentations), roundtable discussions, and Q&A sessions. On the first day, we held a focused session with our Chief Editors to gather feedback and have open discussions on their journal development, the peer-review process, and local accreditation systems.

Impactful Research
50 MDPI Journals Now Indexed in Ei Compendex
Indexing is a key indicator of a journal’s scientific impact. An indexed journal gives research greater visibility and credibility within the global academic community and is recognized for its quality and relevance. While many of our journals are included in major databases such as Web of Science and Scopus, MDPI also places strong emphasis on journal inclusion in subject-specific indexing platforms that align with each journal’s scope. This ensures that when you publish with MDPI, you publish with impact.
I’m pleased to share that as at May 2025, 51 of our journals are now indexed in Ei Compendex, a leading bibliographic database for engineering and applied sciences. This is a major milestone that reflects both the quality or our editorial processes and the relevance of the research we publish in these fields.
“When you publish with MDPI, you publish with impact”
Discoverability and reach
Inclusion in Ei Compendex means greater discoverability for our authors and broader reach of our journals in the fields of engineering and technology. It improves our ability to support global research and innovation, while building MDPI’s reputation in the applied sciences. This recognition is the result of the dedicated work of our editorial teams, reviewers, and authors, and of our overall commitment to excellence in publishing.

Appreciative thanks to everyone involved in reaching this milestone.
Inside MDPI
One Year of MDPI’s Seoul Office
On 29 April, we marked one year since the opening of our Seoul office, MDPI’s first local hub in South Korea. South Korea is a key market for MDPI, currently ranking as our sixth-largest contributor to the company’s total publications, with over 89,000 MDPI articles authored by individuals affiliated with Korean institutions. Over the past 12 months, the Seoul team has made great strides in building our visibility, networks, and presence in the region.
A few highlights from the past year
Claude Seo (MDPI Korea Office Manager, Seoul)
Claude Seo, who has over 15 years of experience in the academic publishing industry, is the Office Manager of the Seoul office.
In its inaugural year, the Seoul office focused primarily on marketing and promotional activities to support the MDPI brand locally. During that time, the team concentrated on scholar visits to local institutions, attending academic conferences, and hosting editorial board meetings.
The team also secured 10 Institutional Open Access Program (IOAP) renewals, signed three new IOAP agreements, and established one new Society affiliation.
The Seoul office also hosted its first library book fair and reached over 1,000 followers on its LinkedIn channel, which is an encouraging indication of local visibility and engagement.

Growth plans
Later this year, we are working on opening a new Seoul office in a more central location, with room for our growing team. The new space will bring us closer to other publishing partners and provide easier access to and from the airport. The Seoul office will continue to expand its efforts in outreach and engagement as its builds its presence in South Korea.
Warm thanks to the entire Seoul team for their hard work and dedication, and to all MDPI colleagues who have contributed to this exciting chapter in our global journey.

Closing Thoughts
Upholding Editorial Independence in Scholarly Publishing
A recent MDPI blog post written by Dr. Ioana Craciun (Scientific Communications Specialist, MDPI), “Editorial Independence and Publisher Support: Collaborating to Uphold Integrity,” highlights the important balance between editorial autonomy and publisher collaboration in academic publishing.
As the leading fully Open Access scholarly publisher, we are proud to champion editorial independence within our publishing process.
Drawing from the Committee on Publication Ethics (COPE) guidelines, the article emphasizes that while editors must have the freedom to make decisions based on scholarly merit, publishers play a critical role in providing the necessary infrastructure and tools to support the editorial process. This collaborative approach ensures the integrity of the peer review process, builds trust among authors and readers, and upholds the quality and relevance of published content.
MDPI highlights its commitment to this model by investing in research integrity specialists, AI tools for plagiarism detection, and administrative support, all aimed at empowering editors to make independent, informed decisions.
