Hi! I am an assistant professor in the Decision, Risk, and Operations division at Columbia Business School. Prior to July 2019, I was a postdoctoral researcher with the Operations Research group at Google Cambridge. In July 2018, I received my Ph.D. from the MIT Operations Research Center, with the pleasure of being advised by David Simchi-Levi.

I spent 2013-2015 as a co-founder of Lunarch Studios, the start-up that designed the strategy game Prismata. During those years, I had also been a research intern with the Ad Exchange team at Google New York, and a trading intern at Jane Street Capital.

I completed my undergraduate degree in 2010 from the University of Waterloo, majoring in Pure Mathematics and Combinatorics/Optimization. During that time, I competed in many international poker tournaments. I founded the poker class at MIT, which can be found on MIT OpenCourseWare.


Revenue Management and Online Assortment Optimization

How should a platform dynamically recommend assortments of products to a stream of customers, when there are finite supplies? These papers analyze this problem from the lens of worst-case performance ratios, under different allocation models, different arrival models, and varying degrees of uncertainty about the customers.

Other Online Algorithms

Other papers analyzing worst-case performance guarantees for online algorithms.
