overview
My research focuses on programming languages, artificial intelligence, and machine learning. My goal is to design systems that make probabilistic modeling fast, accessible, and useful for solving every day reasoning tasks. Broadly my research focuses on:
- The design, implementation, and applications of probabilistic programming languages. I am currently the lead developer for dice; see this blog post for more information.
- Foundations of probabilistic inference and tractable probabilistic modeling. Check out this paper on exploiting symmetry and this paper on unifying probabilistic circuits with determinantal point processes. My group develops rsdd, a high-performance implementation of tractable probabilistic models in rust.
- Automated reasoning and probabilistic verification; see this paper for our latest work on program logics for probabilistic program verification.
