Ph.D. Student in Computer Science · SAND Lab, University of Chicago
I am a third-year Computer Science Ph.D. candidate in the SAND Lab at the University of Chicago, co-advised by Prof. Ben Y. Zhao and Prof. Heather Zheng. My research aims to understand how modern AI systems can be misused and to develop practical tools to study and mitigate those risks. I am excited about problems that revolve around enabling safer and more practical machine learning algorithms.
