research
During my Ph.D., I did research on applied probability, rare events, and connections to statistics and optimization. I was very fortunate to be advised by Kavita Ramanan.

 I recommend reading An Invisible Minority: Asian Americans in Mathematics, written by Sharad Goel and published in the Notices of the American Mathematical Society.
 For a perspective from industry, I suggest The Illusion of Asian Success: Scant Progress for Minorities in Cracking the Glass Ceiling from 20072015, published by Ascend.

perspective
I am broadly interested in applicable mathematics — i.e., theory that can reveal new aspects of the world around us. The following (somewhat conflicting) viewpoints summarize my own perspective:
“I regard as quite useless the reading of large treatises of pure analysis: too large a number of methods pass at once before the eyes. It is in the works of applications that one must study them; one judges their ability there and one apprises the manner of making use of them.”
— J.L. Lagrange
and
“Practical application is found by not looking for it, and one can say that the whole progress of civilization rests on that principle.”
— J. Hadamard
