RESEARCH
My work spans various areas of Mathematics, Theoretical Computer Science, Optimization, and Artificial Intelligence. I aim to tackle some of the most pressing and complex problems at the intersection of computation and society.
At Yale, I co-founded the Computation and Society Initiative.

SUBSTACK The Intelligence Loop
I study foundational questions about algorithmic fairness, privacy, and decision-making, especially in settings where algorithms interact with human judgment, institutional processes, and social norms. My work includes models of bias and strategic behavior in selection systems, as well as the design of equitable and private mechanisms. I also develop mathematical tools for efficient learning in diffusion models, particularly in geometrically structured spaces.
More recently, I have been building theoretical frameworks to understand the impact of AI - such as large language models - on work, science, knowledge, and societal systems. This includes examining how AI alters skill formation, decision structures, and human-AI collaboration, and how we might build more accountable, interpretable, and humane computational systems in response.
I am co-PI of an NSF funded AI Institute: The Institute for Learning-enabled Optimization at Scale
At Yale, I am affiliated to the Cowles Foundation for Research in Economics, the Institution for Social and Policy Studies, and the Thurman Arnold Project at the Yale School of Management.
I served on the Yale AI Task Force.
