MDPI INSIGHTS: The CEO's Letter #23 - MDPI Summits Spain & Italy, Ei Compendex, and Editorial Independence

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 MDPI Spain Summit in Barcelona (21-22 May)

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.


Dr. Giulia Stefenelli (Scientific Communications Lead, MDPI, presents MDPI’s Editorial Process and Peer Review Quality Metrics at the MDPI Spain Summit in Barcelona, 22 May 2025.

I had the pleasure of opening the Summit with a welcome address and an overview of MDPI’s recent milestones. The agenda then included the following sessions:

  • MDPI and Recent Developments in the Spanish Market – Dr. Marta Colomer (Public Affairs Specialist, MDPI)
  • MDPI Editorial Process and Peer Review Quality Metrics – Dr. Giulia Stefenelli (Scientific Communications Lead, MDPI)

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.

You can read our full announcement here.

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.

“The Seoul team has made strides in building our visibility, networks, and presence in the region”

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.
