Eleny Ionel

Eleny Ionel is the Robert Grimmett Professor of Mathematics at Stanford University's Department of Mathematics. She has held significant roles such as Department Chair (2016–2019) and Director of Graduate Studies (2013–2015). Her research focuses on symplectic topology and geometry, particularly holomorphic curves and moduli spaces, with contributions to Gromov-Witten invariants and enumerative geometry.

Education:

• Ph.D. in Mathematics, Michigan State University, 1996
• B.S. in Mathematics, University 'Al. I. Cuza', Iasi, Romania, 1991

Research Interests: Eleny's work centers on symplectic topology, including holomorphic curves, Gromov-Witten invariants, and moduli spaces. She explores connections between symplectic geometry and algebraic geometry, particularly in enumerative problems and gauge-theoretical invariants.

Key Contributions: Her research advances foundational areas like the symplectic sum formula, relative Gromov-Witten invariants, and the Gopakumar-Vafa conjecture. Recent work includes studies on real Gromov-Witten invariants and finiteness conjectures.

Awards & Honors:

• AMS Fellow (2020)
• Simons Fellow (2015–2016)
• Alfred P. Sloan Research Fellow (2000–2004)
• Invited speaker at the 2002 International Congress of Mathematicians

Professional Service: She co-organizes the Northern California Symplectic Geometry Seminar and chairs the Beatrice Yormark Distinguished Lecture Series. She also contributes to editorial roles and conference organization, including leadership in symplectic geometry workshops globally.
