Shubham Sinha

I am a postdoctoral fellow at the International Centre for Theoretical Physics in Trieste, Italy. My mentor is Prof. Alina Marian. I received my Ph.D. from the department of mathematics at the University of California San Diego in June 2023. My advisor was Prof. Dragos Oprea.

Here is my CV.

Research Area: Enumerative algebraic geometry; Algebraic combinatorics. In particular, I am interested in curve counting and enumerative invariants.
