      Collapse Overview
      Dr. An is Associate Professor of Biochemistry and Molecular Medicine at the Keck School of Medicine of USC. His research program is focused on using multi-disciplinary biochemical and cellular approaches to understand fundamental concepts and mechanisms of action of epigenetic histone remodeling in various cellular events. Specifically, his laboratory employs multiple assay systems to dissect molecular details of how histone modifications and variants regulate chromatin structure and control gene expression processes. Current projects involve genome-wide location analysis and functional characterization of histone epigenetic marks during cell growth, differentiation, apoptosis, transformation, and tumor progression. Dr. An received his Ph.D. in Biochemistry and Biophysics in 1998 from the Oregon State University and did his postdoctoral training at the Rockefeller University. He began his career on the faculty at USC in 2004.
