# Anish Agarwal

Assistant Professor, Columbia University

My current research interests are in: (1) causal machine learning; (2) high-dimensional statistics. I am particularly interested in data-driven decision-making in engineering and social systems using tools from econometrics and machine learning.

If you are currently a PhD student or a postdoc at Columbia University and are interested in chatting, please feel free to e-mail me.

# Brief Bio

Most recently, I was a postdoctoral scientist at Amazon, Core AI, before which I was a postdoctoral research fellow at the Simons Institute at UC Berkeley. I did my PhD at MIT EECS, where I was fortunate to be advised by Alberto Abadie, Munther Dahleh, and Devavrat Shah. During the PhD, I interned at Microsoft Research New England with Vasilis Syrgkanis. I also served as a technical consultant to TauRx Therapeutics and Uber Technologies on questions related to experiment design and causal inference. Prior to the PhD, I was a management consultant at Boston Consulting Group. I got my undergrad and master's degrees from Caltech under the supervision of Mani Chandy and Adam Wierman.
