About

I am a final-year Ph.D. student in computer science at University of California, Irvine. My advisor is Prof. Pierre Baldi. My research interests are in computer vision, deep learning, and its applications in physical science.

In particular, my recent projects include:

• generative models for calorimeter simulation
• reconstruction of neutrino features using deep learning
• machine learning in high energy physics
• computational methods for bioimaging and biomedical informatics

Before joining UCI, I graduated with a M.Eng. from University of Illinois at Urbana-Champaign, working closely with Prof. Ruoyu Sun and Prof. Benjamin Hooberman.
