Kostiantyn Drach

Hi, and welcome to my webpage!

My name is Kostiantyn (aka Constantin), or simply Kostya. I am an assistant professor (professor lector) at Universitat de Barcelona and a member of the Centre de Recerca Matemàtica (CRM-Barcelona). 

I am a member of a research group in holomorphic dynamics at UB called HoloDyn.

*New* I'm one of the organizers of the research summer school Topics in Complex Dynamics 2025 (Barcelona, June 1-6, 2025)

I do research in geometry and dynamics. Some keywords are: holomorphic dynamics, hyperbolic dynamics and geodesic flows, rigidity of dynamical systems, renormalization theory, Riemannian and convex geometry, isoperimetric inequalities.
