I am an Assistant Professor in the Edwardson School of Industrial Engineering at Purdue University. My research lies at the intersection of mathematical optimization, stochastic processes, and machine learning, drawing on tools from optimization theory, statistics, and applied probability. I develop adaptive optimization algorithms that are both theoretically grounded and practically effective — enhancing the efficiency and reliability of existing methods, especially in challenging settings involving noisy or messy data.

I am actively seeking motivated PhD students to join my research group. Reach out if you'd like to work with me!

I completed my Ph.D. in Operations Research and Information Engineering at Cornell University, with Professor Katya Scheinberg. Prior to joining Purdue, I was a postdoctoral Principal Researcher at the University of Chicago Booth School of Business, affiliated with the Healthcare Initiative, working with Professor Dan Adelman. I obtained my Bachelor of Mathematics with majors in Pure Mathematics and Combinatorics and Optimization from the University of Waterloo. I completed my Master's degree with Levent Tunçel in Combinatorics and Optimization at the University of Waterloo. Before starting my Ph.D., I worked as a data scientist in Alibaba on the retail supply chain platform team, and prior to that I worked in Baidu and PwC Consulting. In the summer of 2022, I was a Givens Associate in the Mathematics and Computer Science Division at Argonne National Laboratory, working with Stefan Wild and Matt Menickelly.
