I am an assistant professor in Mathematics at the National University of Singapore

My PhD Adviser is Adrian Lewis.

Recently, I am working on accelerating the method of alternating projection
methods. I was also working on work on set-valued analysis and applying the
theory to Differential Inclusions (which encompasses Optimal Control and the
Calculus of Variations; More honestly, I worked on the discretized problem, and
I hope to come back to that soon). Some of these topics fall under what is now
known as Variational Analysis. In the past, I worked on
semi-algebraic Variational Analysis, Numerical
methods for the mountain pass, and Pseudospectra.
