I am an Associate Professor at the University of Southern California working on symplectic topology. Much of my recent work concerns structural aspects of Fukaya categories and Floer theory, using methods of homological algebra and non-commutative geometry, with applications to mirror symmetry and string topology.

In 2023-2024 I am on sabbatical, supported by a Simons Fellowship. I also gratefully acknowledge the support of the National Science Foundation through Awards DMS-1907635, DMS-2002137 and CAREER DMS-2048055.

More details can be found in my CV (last updated 12/2023).
