Zekai Wang

I'm an undergraduate at UC Berkeley studying Computer Science and Applied Mathematics, graduating in December 2026. I am fortunate to be advised by Professor Trevor Darrell at Berkeley AI Research (BAIR).

I work on data-centric robot learning for dexterous manipulation, designing model architectures, training paradigms, and infrastructure around the hierarchy of human, robot, and online interaction data. I'm applying to PhD programs in the 26-27 application cycle.
