I am an assistant professor in the Department of Mathematics at National Taiwan University. Before NTU, I was a Dunham Jackson assistant professor (postdoc) in the School of Mathematics at University of Minnesota. I graduated from Indiana University in 2018.

This poster briefly explains my work on two dimensional critical first-passage percolation (1 and 4 above).

Simulations of some stochastic spatial models.

In Spring 2018, I organized a graduate student seminar on random matrix theory. Click here for the notes.
