**About me**:
I am a Limited Term Assistant Professor at the University of Georgia.
My research
is primarily in algebraic geometry. In particular, I am mainly interested in geometric and arithmetic properties of moduli spaces, and also interested in enumerative problems. See my
research statement for more details on my mathematical interests.

I got PhD degree in Mathematics at Harvard University. My graduate advisor is Joe Harris.

Here is my
CV.
