Dennis Assanis — who has led the University of Delaware since 2016 during a unique period of transformation and growth — announced today that he will step down from the presidency on June 30.

Assanis, UD’s 28th president, led the University with a deep commitment to academic excellence and student success, a drive to expand world-class research, scholarship and innovation, and a determination to translate knowledge into beneficial impact for all. As a distinguished educator, renowned scholar and seasoned administrator, Assanis has energized the University as a hub for global education and engagement, expanding resources and opportunities for students, faculty and staff to thrive in a rapidly changing world.

“My wife, Eleni, and I are so grateful to everyone in the University of Delaware community, whom it has been my distinct honor to serve as president. Our hearts are filled with gratitude and pride,” said Assanis. “UD is a remarkable place with a vibrant culture of interdisciplinary inspiration to reimagine what’s possible in higher education. I will forever treasure my experience of leading such an extraordinary institution defined by amazing students, talented faculty, dedicated staff and a vast network of loyal alumni and friends who support its mission.”

Board of Trustees Chair Terri Kelly said, “I want to thank Dennis Assanis for his inspiring leadership and service as the University of Delaware’s 28th president. His tireless commitment and bold vision have been transformative, advancing the University to new levels of accomplishment, promise and potential. As we look ahead to the next chapter in the University’s leadership, President Assanis’ legacy of purpose-driven, positive change will forever have an impact on UD’s continued future of institutional excellence. We wish him and Eleni nothing but the best for their future.”

Kelly said the announcement of an interim president to serve beginning July 1 will be forthcoming.

A Campus Transformed

As president, Assanis collaborated with leaders across the University to solidify and advance the Forward and Forever strategic plan, designed to position UD for continued excellence, growth and transformative impact. With its foundational commitment to student success, inclusive excellence, interdisciplinary work on a global scale, innovation and entrepreneurship, and ongoing investment in the intellectual and physical capital of the University community, the strategic plan presented a robust vision for a campus on the move.

Of note, the upward trajectory of UD’s institutional progress has continued to be recognized across multiple national rankings. This momentum has been achieved and sustained throughout his presidency in spite of unprecedented challenges posed to higher education over the past several years, including the COVID-19 pandemic. The University is ranked #26 among 500 U.S. colleges and universities (up 60 spots from the year before) and #10 out of 235 public universities in The Wall Street Journal/Pulse Rankings 2025, and #86 among 434 national universities by U.S. News & World Report 2024-25. Earlier this spring, UD’s top-ranked graduate programs announced by U.S. News & World Report included 13 programs ranked among the top 50.

Some key outcomes of President Assanis’ leadership and influence include:

Commitment to Student Success

Assanis introduced initiatives aimed at expanding access, affordability and pathways to success for all students, as well as improving pipeline programs and lifelong learning opportunities. His prioritization of academic excellence has translated to an impressive four-year graduation rate that has placed UD ninth in the nation among other public R1 institutions, as reported in the IPEDS 2022-23 Graduation Rate Survey, 2016 cohort. Also, undergraduate financial aid at UD has increased by more than 95% since 2016, from $94 million to $185 million. Throughout his tenure, applications to the University achieved record levels, translating to all-time high enrollments across all categories of students (in-state, out-of-state, honors, graduate, international, transfer). Of note, this is the sixth consecutive year that UD has received a record number of first-year student applications, now exceeding 41,000 and 50% more than when Assanis started his tenure.

In addition, to enhance socioeconomic mobility and student success, he introduced the First State Promise program, which aims to cover all tuition and fees for Delawarean undergraduate students coming from families with incomes under $75,000. About one-third of enrolled Delawareans are covered by First State Promise. Also, since 2016, enrollment of Pell-eligible students has increased by more than 34%, and enrollment of underrepresented minority students has increased by more than 30%. 

Assanis also led enhancements of student life, increasing support for mental health services and fostering a culture of inclusion. For example, a new Wellbeing Center at the renovated Warner Hall is driving a more holistic approach to health, wellbeing and counseling for students. In parallel, he supported the creation of programs and physical spaces that encourage and enable all members of the University community to connect, learn, grow and collaborate, including the Center for Intercultural Engagement. Assanis also established the President’s Student Advisory Council to assemble student leaders from across campus for interactive discussion regarding pressing needs and opportunities for the University.

As an advocate for innovative learning, Assanis has supported creation and expansion of programs on UD’s multiple campuses in Delaware, as well as through institutional partners around the world. For example, building on the success of the Associate in Arts Program, he fostered new academic opportunities and facilities for students. As former international students themselves, both President and Mrs. Assanis actively promoted and supported expansion of the UD World Scholars Program by adding sites at the American College of Greece in Athens, the University of Auckland in New Zealand, and Newcastle University in England.

Academic and Research Excellence

As president, Assanis fostered transformational growth of UD’s research, scholarship, and innovation. Total research expenditures from all sources increased by more than 160%, from $176 million in FY16 to $466 million in FY24. During his tenure, UD’s rankings in the most recent Higher Education Research and Development (HERD) survey released by the National Science Foundation improved from #59 to #28 among publics, and from #84 to #45 among 626 academic institutions, when comparing non-medical school R&D expenditures. Research and scholarship have expanded across various disciplines, evolving through interdisciplinary collaboration, academic focus, human relevance, and societal impact.

One catalyst for growth has been UD’s role as headquarters for the National Institute for Innovation in Manufacturing Biopharmaceuticals (NIIMBL), which Assanis helped secure in 2016. Also during his tenure, UD has created and/or renewed multiple interdisciplinary centers and institutes in innovative materials, clean hydrogen and environment, biomedical and life sciences, engineering driven health, education and policy. Assanis has also worked closely with various campus stakeholders to support numerous and emerging campus-wide artificial intelligence (AI) initiatives in academics, research, operations and ethics. He also created a policy to invest campus resources in support of the growth of the Arts and Humanities, emphasizing the comprehensive nature of the University and the importance of holistic education.

Throughout his tenure, Assanis worked closely with the provosts, deans and chairs to spearhead an unprecedented effort to enhance UD’s faculty ranks, hiring more than 600 faculty across campus since 2016, including several in interdisciplinary clusters. About 45% of current faculty members have been hired since 2016, bringing new perspectives, energy and diversity to UD’s distinguished faculty ranks. Their collaborative efforts have yielded multi-year faculty hiring plans to meet projected demand for undergraduate and graduate student instruction across multiple departments and colleges at the University, based on growth in enrollment and research opportunities.

In addition, Assanis elevated the undergraduate Honors Program to the Honors College, recognizing its excellence and interdisciplinary standing. The Honors College is currently receiving more than 16,000 applications for 800 honors placements in the first-year class. Over a 10-year average, the four-year graduation rates for UD’s honors students are 88% across the entire cohort. In parallel, he placed a renewed commitment on graduate education and research by launching the Graduate College to promote excellence and the creation of new interdisciplinary programs.

Assanis also catalyzed the naming of UD’s stand-alone, highly ranked Joseph R. Biden, Jr. School of Public Policy and Administration, enhancing the school’s programs and impact through partnerships with many of the colleges and the community, including the creation of the Biden Institute at UD and the Stavros Niarchos Foundation Ithaca Initiative on civil discourse and civic engagement.

Assanis continued to nurture campus-wide participation in Horn Entrepreneurship, evolving it into a highly ranked program, currently rated as #3 in the Mid-Atlantic by Princeton Review. The Assanises have been strong supporters for the elevation of the School of Music, raising resources and expanding its community outreach. The introduction of the Calidore String Quartet and the global ambassadorship of the Delaware Choral Scholars are exemplars of the school’s excellence in both academics and performance.

Campus Evolution

Assanis has been an active champion for the vision to develop UD’s Science, Technology and Advanced Research (STAR) Campus as a nexus for cutting-edge discovery and innovation, top-notch academics, community partnerships, entrepreneurship and economic development. He has led initiatives to make STAR home to more than 1.2 million square feet of new buildings where more than 3,000 people work. Significant investment by UD and its partners over the past nine years have helped create the Tower at STAR, the Ammon Pinizzotto Biopharmaceutical Innovation Center, Chemours’ global R&D Discovery Hub, the FinTech Innovation Hub and the Securing American Biomanufacturing Research and Education (SABRE) Center, currently under design. Powered by changemakers with big ideas, the STAR Campus community is accelerating innovation in health, energy and environment, financial technology and data science services, rapidly elevating UD’s prominence and impact as a 21st-century research university.

Other areas of campus, including the historic Green, have been transformed as well. Completed projects under Assanis’ leadership include the new interdisciplinary science center, known as Building X, which brings together brain science, biological science and quantum science; the renovation of Worrilow Hall; the addition of Joseph and Judith DeStefano Chemistry wing to Drake Hall; the renovation of the Design Studio; the Pearson Hall Makerspace; numerous classrooms, laboratories and significant spaces for music, theater and dance; the opening of the South Academy Residence Hall; and the acquisition of the University Courtyard apartments.

As a leader and connector, Assanis significantly advanced University relationships with multiple constituents throughout his presidency, yielding consistent increase in philanthropy and federal and state appropriations for capital projects.

Record-Breaking Philanthropy

Throughout his tenure at UD, Assanis brought a strategic and deliberate approach to philanthropic development, crafting a vision and case statements in support of institutional priorities and capital projects. Together with his wife, Eleni, the Office of Development and Alumni Relations and multiple units across campus, Assanis prioritized deep relationships with major philanthropic donors and prospects to support life-changing UD initiatives in alignment with institutional evolution and impact.

One year into his presidency, the University launched the most comprehensive fundraising and engagement campaign in its 282-year history, Delaware First, garnering more than $1 billion to support scholarships, faculty research and campus infrastructure and programming. The campaign drew support from more than 113,000 donors, fueling growth and discovery for generations of Blue Hens. In 2020 and 2022, UD’s outstanding philanthropic campaign was recognized as the winner of two National Circle of Excellence educational fundraising awards.  Since the completion of the campaign, UD has raised more than $270 million in two and a half years to support scholarships, student success and capital projects. Among them, in March of this year, the University announced the largest donation in its history — a $71.5 million commitment from UD alumni Rob and Kathy Siegfried to create Siegfried Hall, a state-of-the-art, student-centric learning space, and the Siegfried Institute for Leadership and Free Enterprise as part of UD’s Alfred Lerner College of Business and Economics.

Elevating Athletics

Throughout his presidency, it was not unusual to see the Assanises cheering on Blue Hen student-athletes from the stands. Under the president’s leadership, the University saw the renovation and construction of new athletic facilities — including an upgrade of UD’s 22,000-seat Delaware Stadium and construction of the new Whitney Athletic Center, integrating student-athlete development. In 2023, the University announced its move to Conference USA and the football team’s transition to FBS, which will be a game-changer for UD athletic competition. In addition, the University will add women’s ice hockey as a varsity sport.
