Scholar-generated biography
Stefanos Aretakis is an Associate Professor at the University of Toronto, specializing in Partial Differential Equations, Differential Geometry, and Mathematical Physics. His research focuses on the stability and instability of extremal black hole spacetimes, particularly under scalar perturbations. Aretakis investigates late-time asymptotics, horizon instabilities, and nonlinear dynamics of extremal Reissner–Nordström and Kerr black holes. His work explores the behavior of waves on curved spacetimes, including decay properties and mode coupling. He also contributes to the characteristic gluing problem and conservation laws for the wave equation on null hypersurfaces. His research has significant implications for understanding gravitational wave propagation and black hole dynamics in general relativity.
