Postdoctoral Scientist,

I am a postdoctoral scientist at Amazon within the Supply Chain Optimization Technologies (SCOT) group. I will join the Department of Data Sciences and Operations at USC’s Marshall School of Business as an assistant professor in Fall 2023.

My research focuses on the design of efficient, provably good algorithms for online decision-making problems, with applications to inventory management, pricing, and transportation.

I obtained my Ph.D. in Operations Research at Cornell University, where I was fortunate to be advised by Professor Siddhartha Banerjee. Prior to that, I obtained my B.S.E. in Operations Research and Financial Engineering from Princeton University, with a minor in Applied Mathematics.
