Assistant Professor |School of Medicine   Research Group

Ruilin Tian is an assistant professor in School of Medicine, SUSTech. Ruilin completed his bachelor's degree in biological sciences at Peking University in 2015. He obtained his PhD degree from University of California, San Francisco (UCSF) in June 2020 in Dr. Martin Kampmann’s lab. After that, he continued his postdoc training in Martin’s lab. Ruilin joined SUSTech in the end of 2020.

During his PhD and postdoc, he pioneered a CRISPR-based functional genomics platform in human iPSC-derived neurons, which enables genome-wide modifier screens of disease-relevant cell biology to uncover disease mechanisms and identify novel therapeutic strategies.

The Tian lab’s research focuses on understanding cellular and molecular mechanisms of human diseases, especially neurodegenerative and neurodevelopmental disease, using innovative genomics and cell biology technologies. Our lab also develops new CRISPR-based functional genomics tools to facilitate our biomedical research.
