Hi! I am Chaoran Cheng, a third-year CS Ph.D. candidate at the University of Illinois Urbana-Champaign. I am advised by Prof. Ge Liu, before which I was working with Prof. Jian Peng. My research interest mainly spans multiple AI4Science topics with a special focus on generative tasks on 3D molecules and proteins including sequence-structure co-design and structure optimization. Combining both the continuous and discrete modalities together, our work can build a more comprehensive and versatile generative model for molecules and proteins on diverse downstream tasks.

Out of my pure personal interest, I am developing a machine-learning based automatic charter for Cytoid, a community-driven rhythm game inspired by Rayark’s games Cytus and Cytus II. The community provides many fan-made charts that can be used to train a machine learning system.

I obtained my Bachelor’s Degree in EECS, Peking University, before which I also spent my freshman year studying chemistry.
