Shawn Liu, PhD
- Joan and Paul Marks, MD '49 Assistant Professor of Physiology and Cellular Biophysics
Xiao Shawn Liu received his B.A. in Chemistry from Nankai University in China. He completed his Ph.D. training at Purdue University and Stanford University focusing on the signal transduction mediated by protein kinases and ligand-receptor interactions. As a Damon Runyon Postdoctoral Fellow in Rudolf Jaenisch’s laboratory at Whitehead Institute MIT, Shawn developed a series of epigenome editing tools to systematically investigate the functional significance of epigenetic modifications in neurological disorders. In 2019 he joined the Department of Physiology and Cellular Biophysics at Columbia University as a Paul A. Marks assistant professor to start his independent research career.

Our laboratory aims to decode the epigenome in physiology and diseases. We combine molecular tool development with genetic and genomic approaches to explore epigenetic mechanisms underlying normal physiological functions, and to uncover the epigenetic basis of diseases to accelerate the development of therapeutics. We mainly use human ESC- or iPSC-based system and genetically engineered mouse models to tackle these questions. Our three major research directions are listed below as 1) CRISPR-based epigenome editing tool development; 2) Molecular basis of memory storage; 3) Tackle human disease by sculpting epigenome.
