Chuan He is the John T. Wilson Distinguished Service Professor in the Department of Chemistry and Department of Biochemistry and Molecular Biology at the University of Chicago.He received his B.S. (1994) from the University of Science and Technology of China. He received his Ph. D. degree from Massachusetts Institute of Technology in chemistry in 2000. After being trained as a Damon-Runyon postdoctoral fellow at Harvard University from 2000-2002, he joined the University of Chicago as an Assistant Professor, and was promoted to Associate Professor in 2008, Professor in 2010 and John T. Wilson Distinguished Service Professor in 2014. He is also a member of the Cancer Research Center at the University of Chicago. His research spans a broad range of chemical biology, RNA biology, epigenetics, biochemistry, molecular biology, and genomics. His recent research concerns reversible RNA and DNA methylation in biological regulation. His research group discovered the first RNA demethylase and showed that reversible RNA methylation significantly affects gene expression regulation.
