About

I am a Ph.D. student in Computer Science at Cornell University advised by Professor Jennifer Sun, specializing in AI for science. My research focuses on developing AI tools that accelerate scientific discovery by addressing practical scientific bottlenecks. I am also a visiting student researcher at the HHMI Janelia Research Campus in the Branson lab, where I have worked on methods to benchmark AI-driven scientific discovery.
