I am a research manager at the MIT-IBM Watson AI Lab where I lead the Statistical Large Language Modeling group. I am interested in a variety of LLM-related problems (evaluation, alignment, routing, fusion, prompt engineering, UQ, data quality) and I like to explore statistical modeling approaches to them. I have also worked on OOD generalization, Algorithmic Fairness, Optimal Transport, Federated Learning, and Bayesian nonparametrics.
