My research lies at the intersection of statistics, optimization, and machine learning. I work on developing computationally efficient and statistically powerful algorithms with guarantees, for engineering problems arising from various real-world applications.
My work has generated societal and policy impact: see here for our work on data-driven policing.
For recent publications and preprints, please see here. My Erdős number is 3.
