I am a 6th Year Ph.D. student at UW-Madison advised by Theodoros Rekatsinas and Shivaram Venkataraman. My undergraduate degree was in Applied Math, Engineering and Physics (AMEP). My research interests lie in the intersection of systems, databases, and machine learning. I work on indexing and query processing for vector search. Previously, I worked on the graph learning system Marius. I am the lead developer of the vector search system Quake.
