I am an assistant professor at Stanford in the Department of Statistics (and in Computer Science, by courtesy).

My research is at the intersection of theoretical computer science and statistics.
My work aims to develop algorithmic tools for high-dimensional estimation problems and to characterize and explain information-computation tradeoffs.

Before joining Stanford,
I received my PhD from U.C. Berkeley, where I was lucky to be advised by
Prasad Raghavendra and
Satish Rao.
After that I was a postdoc at Harvard and MIT, hosted by the wonderful quadrumvirate of Boaz Barak, Jon Kelner, Ankur Moitra, and Pablo Parrilo.
Here is a tutorial for pronouncing my name.
