Soham Chanda (সোহম চন্দ)

I am a Herbert and Ruth Busemann Assistant Professor (postdoc) at the University of Southern California from 2024-2025 and will continue as an RTPC Professor (postdoc) until 2027. I obtained my PhD from Rutgers under the guidance of Chris Woodward. My CV can be found here.

Research interest

My research interest lies in symplectic and contact topology. My most recent work constructs a family of new surgery operations on Lagrangians and studies it's effect on Floer theoretic invariants of monotone Lagrangians.

In particular, I use tools inspired from SFT to understand how changing fillings affect Floer theoretic invariants. This approach lets me leverage contact-geometric data of Legendrian to obtain results about Lagrangian manifolds and vice versa.
