I am a mathematician working in geometry.

Research interests: Global analysis on manifolds and complex geometry. My most recent work deals with asymptotic problems in complex geometry; some of my previous writings are related to the Atiyah-Singer index theorem, local index theory, semi-classical analysis, pluripotential theory and probability theory.

Current position: Researcher (chargé de recherche) in CNRS. Professeur chargé de cours d’exercice incomplet, Centre de mathématiques Laurent Schwartz, École Polytechnique, Palaiseau, France.

Previous positions: From September 2019 to October 2021, I was a postdoctoral researcher at Université Grenoble Alpes, France, working under the direction of Jean-Pierre Demailly. Prior to that, I was a graduate student at Université Paris Diderot, France, working under the direction of Xiaonan Ma.
