Kai Fu

Kai Fu is a postdoctoral researcher at the Max Planck Institute for Mathematics in the Sciences in Leipzig, working in the Geometry, Groups, and Dynamics group led by Anna Wienhard since 2025.

He earned his PhD from the Institut de Mathématiques de Bordeaux under co-advisors Vincent Delecroix and Elise Goujard in the Geometry group.

His research centers on real two-dimensional manifolds (surfaces) and moduli spaces, with specialized focus on holomorphic/meromorphic Abelian differentials and flat cone surfaces. He applies combinatorial techniques including Delaunay triangulations to analyze saddle connections, cylinder counting problems, and moduli space compactifications, bridging differential geometry, topology, and computational methods.

He operates within the Geometry, Groups, and Dynamics research framework at the Max Planck Institute for Mathematics in the Sciences.
