My research focuses on programming languages, artificial intelligence, and machine learning. I am part of the Programming Research Laboratory at Northeastern University, and I guide the Northeastern Probabilistic Programming Laboratory (NeuPPL).

What excites me is the challenge of designing systems that make probabilistic modeling fast, accessible, and useful for solving every day reasoning tasks. Broadly my research focuses on:
