Teaching: Autumn 2019: Math 350, Introduction to Manifolds

About me: I am an instructor at Princeton University. I finished my PhD at UCLA in 2017. My advisor was Ciprian Manolescu.

I study low dimensional topology using symplectic geometry.

My research is partially supported by an NSF Postdoctoral Research Fellowship (grant DMS-1703685).

Here is my CV
