Ray R. Liu

I am a research associate at Zhang Lab at CMU, working on applying statistics and machine learning on single-cell multiome data to discover enhancer-gene associations. I also work on AI agents for scientific discovery. I have a Master's in Computational Biology from CMU School of Computer Science. I did my undergraduate at Tsinghua University majoring in Mathematics and Physics with Computer Science track. I also spent a summer as a ML research intern at Mila-Quebec AI Institute advised by Prof. Jian Tang, working on TorchDrug and TorchProtein.

I am actively looking for full-time AI/ML roles starting in 2026.

Miscellaneous

I have a unique background: I was born in Japan, living between Japan and China since then. I am also very proud and blessed to have a brother who studies Computer Vision at MIT. He is like my life mentor, motivating and inspiring me to become a better person.

Besides, I love playing tennis. I was the tennis team captain in the Physics department at Tsinghua. Huge fan of Roger Federer, the GOAT in Tennis. He is my second biggest inspiration in my life. "Dream big and work hard", and "Shoot for the star and you will land on the moon" are my favorite quotes from him. Also, check out my YouTube playlist for some of the most unique moments of Roger's career.
