About Me

I am a researcher and software engineer with a focus on understanding and solving challenging decision making problems by using techniques from Machine Learning, Optimization, and Statistics.

I’m currently the tech lead for the CPG Ad Economics team at DoorDash. We design and maintain the algorithms behind ad auctions, budget pacing, and autobidding products. Before that I spent a couple years at LinkedIn working on privacy-related problems. Before joining industry I got a Ph.D. in Operations Research at Georgia Tech where I studied Machine Learning, Online Convex Optimization, and Bandit Problems.
