I am a postdoctoral fellow at the Harvard Center for Research on Computation and Society hosted by Cynthia Dwork. I received my PhD in EECS from UC Berkeley, where I was co-advised by Peter Bartlett and Moritz Hardt, and my BA in CS and Math from Harvard.

I am on the job market this 2024-2025 academic year

Research Overview. My research centers on machine learning in social systems, exploring how learning algorithms can be used both to detect and shape social patterns. I organize my work around a mix of both theory and empirically driven directions, including performative prediction and the study of prediction in resource allocation problems.

About. I was born and raised in San Juan, Puerto Rico where I was on the national sailing team. I won youth world championships at the under-17, 19, and 21 levels and represented Puerto Rico at the 2015 Pan American Games. I also worked on the design team during Emirates Team New Zealand's winning campaign for the 35th America's Cup in Bermuda.
