I am an Assistant Professor at MIT. Here is my CV.
My research focuses on symplectic topology, though my research projects are related to or inspired by nearby fields, including low-dimensional topology, algebraic geometry, algebraic topology, dynamics, and, more recently, arithmetics.

Organization and Service
Guangbo Xu and I organized Rutgers Symplectic Summer School 2024 and 2025.
I served as a mentor for the 2024 Kylerec workshop.
I co-organized Columbia Symplectic Geometry and Gauge Theory Seminar.
I co-organized a learning seminar on Enumerative invariants and birational transformations with Patrick Lei.
