I am a researcher (chargé de recherche, CNRS) in Center of Mathematics Laurent Schwartz, École Polytechnique. From September 2019 to October 2021, I was as a postdoctoral researcher in Université Grenoble Alpes, France, working under the direction of Jean-Pierre Demailly. Prior to that I was a graduate student in Université Paris Diderot, France, working under the direction of Xiaonan Ma.

Research interests:

I am mainly interested in global analysis on manifolds and complex geometry. Based on the methods from those areas, my work relates to Atiyah-Singer theorem, local index theory, semi-classical analysis and probability theory.

Currently I'm working on extension problems in complex geometry and their applications.
