Jianhong Tu

First-year Comp. Sci. PhD student @ UCSC

I am a first-year PhD student in Computer Science at University of California, Santa Cruz, advised by Dr. Chenguang Wang. I am also a post-training researcher with the Amazon Nova AI Challenge at UC Santa Cruz. Before that, I completed my Bachelor’s degree in Data Science at Washington University in St. Louis, where I was a student researcher at the Hengen Lab, supervised by Dr. Keith Hengen and Dr. James McGregor.

My research interests lie in foundation models, post-training, agentic AI, and cybersecurity. Outside my lab, I enjoy city-pop music and hiking.
