Hi! I am a rising fourth year PhD student at Princeton Computer Science advised by Tom Griffiths. The central focus of my research is how large language models can transform how our society communicates and learns information. Previously, I was a Masters student at Carnegie Mellon working with Nihar Shah on solving central problems in conference peer review.
I am happy to chat about my current research and future opportunities! Please contact me via email at ryanliu@princeton.edu.
