Research

Rietsch's research concerns the geometry of flag varieties, the mirror symmetry of Calabi–Yau manifolds, the theory of Gromov–Witten invariants, Lie theory, and quantum cohomology. [1] She is particularly known for her "foundational works" in the 1990s with George Lusztig, introducing the positive Grassmannian. [2]

Beyond pure mathematics, Rietsch is a member of the Music and Acoustics Research Centre at King's College London. [3] She has studied the music theory of the Tonnetz and has collaborated with Elaine Chew in a new musical composition based on her theoretical work in this area. [4]

Education and career

Rietsch received a master's degree in 1993 from the University of Vienna in 1993, with a master's thesis on Lie theory. She completed a Ph.D. in 1998 at the Massachusetts Institute of Technology. [1] Her doctoral dissertation, Total Positivity and Real Flag Varieties, was supervised by George Lusztig. [5]

Following her doctorate, she visited the Institute for Advanced Study in Princeton, New Jersey, [6] and became a postdoctoral research fellow in Newnham College, Cambridge. [7] Next, she became a Violette and Samuel Glasstone Research Fellow at the Mathematical Institute, University of Oxford. [8]

She moved to King's College in 2002. As well as being Professor of Geometry there, she is deputy head of the mathematics department for education, and a governor of the King's College London Mathematics School. [9]

Recognition

Rietsch is an invited speaker at the 2026 International Congress of Mathematicians. [10]
