Hi there!
I am a Senior Director of Machine Learning Engineering at Instacart in San Francisco, California. Working at the intersection of economics and machine learning, my team and I tackle a diverse set of topics, including ads, pricing, and growth.
You can contact me through LinkedIn.
Research
I have worked as a postdoctoral researcher in economics at Stanford University under the supervision of Prof. Susan Athey and as a postdoctoral researcher at the Bonn Institute for Applied Microeconomics.
My research focuses on applied microeconometrics, machine learning, and behavioral finance, with particular emphasis on user heterogeneity, dimension reduction in choice models, and the estimation of price elasticities. I am also interested in the role of beliefs and non-standard choice behavior in financial decision making.
