Black Holes & General Relativity

Dr. Stefanos Aretakis is an Associate Professor at the University of Toronto, specializing in differential geometry, geometric analysis, partial differential equations, and general relativity. His research focuses on the stability and instability of black holes, particularly extremal black holes, and the behavior of wave equations in curved spacetime. His work has led to the identification of instability phenomena now known as the "Aretakis instability."

He has authored numerous research papers on the dynamics of black holes, late-time wave behavior, and scattering theory, published in journals such as Advances in Mathematics, Communications in Mathematical Physics, and Classical and Quantum Gravity. He has also written books on mathematical general relativity and extremal black hole dynamics.

Dr. Aretakis has supervised PhD students and postdoctoral researchers and has taught courses on topics including real analysis, combinatorics, and geometric analysis. He has delivered invited talks at institutions such as Princeton, Harvard, and Cambridge and has received awards including the IUPAP Young Scientist Prize in Mathematical Physics and the Bodossaki Distinguished Young Scientist Award.
