I am a Ph.D. student in Computer Science at Johns Hopkins University, advised by Prof. Mathias Unberath. Before that, I earned an M.S. in Biomedical Engineering from Johns Hopkins University in 2023 and a B.S. in Biomedical Engineering from University of California, Davis in 2022.

I build digital twins of the operating room as the foundation for robotic surgical assistance.
