I am an Assistant Professor at the University of Southern California. My interests include smooth dynamical systems, symplectic topology, manifolds and symplectic field theory.

I was previously an NSF Postdoctoral Fellow jointly in Princeton and IAS from 2021 to 2023. Prior to that, I was a UC President's Postdoctoral Fellow at UCLA in 2021.

I received my PhD at the University of California, Berkeley in 2021 under the supervision of Michael Hutchings .

I have been awarded the Herb Alexander Thesis Prize, the NSF Graduate Fellowship, the UC Chancellor's Fellowship, and the Rose Hills Foundation Fellowship.
