Through a unifying framework, with the power of continuous relaxations (beyond convexity) and primal-dual certificates, my research group produces novel algorithms for learning and inference in combinatorial problems. Our aim is to generate correct, computationally efficient and statistically efficient algorithms for high dimensional machine learning problems. Our results pertain not only to classical worst-case NP-hard problems, such as learning and inference in structured prediction, community detection and learning Bayesian networks, but also to areas of recent interest such as fairness, meta learning and federated learning.

Prior to joining Purdue, I was a postdoctoral associate at MIT CSAIL, working with Tommi Jaakkola. My Erdős number is 3: Jean Honorio → Tommi Jaakkola → Noga Alon → Paul Erdős.
