I am a postdoc in the Theory of Computation group at MIT, fortunate to be hosted by Sam Hopkins. I am supported by FODSI. I am generally interested in theoretical computer science and probability theory. Most recently, I have been interested in the algorithms and complexity of inference problems. If you happen to encounter any of my work, feel free to reach out: questions and feedback are highly appreciated!

My PhD education was in the Theory Group at UC Berkeley, under the amazing guidance of Prasad Raghavendra.

My undergraduate education was at Carnegie Mellon University where I was lucky to be advised by Ryan O'Donnell.
