Ph.D. in Mathematics from Université Pierre et Marie Curie (Paris, France, 2000), M. Sc. in Partial Differential Equations and Scientific Computing from Université Paris-Sud Orsay (1996), M.Sc. in Finance from Université Paris Dauphine (2002), Habilitation à Diriger des Recherches from Université Pierre et Marie Curie (2007). Was Maître de Conférences at Université Paris Nanterre and Associate Researcher at École des Hautes Études en Sciences Sociales (Paris, France) until 2012. Currently is a professor at Pontifícia Universidade Católica do Rio de Janeiro, Chair of its Graduate Program in Mathematics. Works on analysis and applications of elliptic and parabolic partial differential equations.
Boyan Sirakov's research focuses on elliptic and parabolic partial differential equations. He studies existence, uniqueness and regularity in Sobolev and Holder spaces of solutions of such equations, as well as eigenvalue problems, maximum principles, Harnack inequalities, qualitative properties of solutions, fundamental solutions, Liouville type theorems, singularity classification, by using variational and topological methods and viscosity solutions. He also works on modeling natural and financial phenomena through partial differential equations, in particular model of fluid flow in petroleum engineering.
