Research Fields:
I am mainly interested in the global analysis on manifolds, especially, local Atiyah-Singer index theory, complex geometry and semiclassical analysis.
Position:
I was a PhD student at Université Paris Cité, France, working under the supervision of Prof. Xiaonan Ma. In August 2022, I joined Penn State University as a postdoctoral researcher under the direction of Prof. Nigel Higson. I will join Texas A&M University as a Visiting Assistant Professor in August 2024, working with Prof. Sherry Gong and Prof. Guoliang Yu.
