On this site I provide information on my background, research, and few random thoughts. I am an economist at Microsoft Research in New York City. I have a Ph.D. in applied economics from the Wharton School of Business at the University of Pennsylvania. I have written extensively, in both the academic and popular press. My work pushes the boundaries on varying data and methods: large language models, polling, prediction markets, social media and online data, and large behavioral and administrative data. The work focuses on solving practical and interesting questions including: interactions of humans and LLM-based tools, mapping and updating public opinion, the market for news, effect of advertising, finance, and an economist take on public policy.

I am also a Co-PI for PennMap at University of Pennsylvania.
