About Me

Hi! I am an Assistant Professor at Columbia Business School in the Decision, Risk, and Operations division and a member of the Data Science Institute.

Previously, I received my PhD in Operations Research from Stanford University, where I was affiliated with the Operations Research group in MS&E and the Society and Algorithms Lab. I was a postdoctoral associate at MIT. I graduated from Pomona College with a degree in mathematics.

Research Interests

My research develops data science methods tailored to social systems, such as online marketplaces, education systems, social media, and digital health platforms. In particular, I focus on experimentation, recommendation systems, and early warning systems.

My work combines interdisciplinary approaches from operations research, statistics, causal inference, and economics to develop practical solutions with theoretical guarantees. I inform my research with collaborations and first hand experience working with these platforms.
