Chumeng Liang

PhD student in Computer Science, University of Illinois, Urbana-Champaign.

I work on generative models and representation learning, with my current focus on diffusion language models. I am more than fortunate to be advised by Prof. Jiaxuan You. I also work closely with Prof. Ge Liu.

Previously, I obtained my M.S. from the University of Southern California and B.S. from Shanghai Jiao Tong University, where I worked on relieving copyright concerns of generative models.
