Research Interests

I develop theoretically sound approaches to problems in machine learning, with the goal of making AI more trustworthy and robust. Recent directions include problems in scaling up causal structure learning, leveraging optimal transport in machine learning, and neural network generalization theory.

Keywords: Machine learning, information theory, causal inference, optimal transport, statistical learning theory, signal processing, contextual bandits, time-varying models, high dimensional data, estimation theory.
