Colin Zhao

I study CS at Penn, with an interest in AI alignment, evals/environments, and RL.

Currently, I'm a MTS intern at Refresh, building harnesses and evals for computer-use agents. Previously, I conducted research with Tessa Cook on self-improving agent frameworks for radiology, and built browser-use benchmarks under Vincent Liu.

When I'm not coding, I enjoy taekwondo, reading manga, and lifting.
