Short Biography:

Dr. Wells received his B.S. in Chemistry, with a minor in Psychology, in 1991 from the Georgia Institute of Technology, and after spending two years working at the Microchemical Facility, his Ph.D. in Biochemistry and Molecular Biology in 1998 from the Emory University School of Medicine. A postdoctoral research fellowship at the Johns Hopkins School of Medicine in Biological Chemistry followed, which was supported by a National Research Service Award from the National Cancer Institute of the NIH. Dr. Wells joined the CCRC in August of 2003. Full publications: 98.

Research Interests:

Using a combination of methodologies, including mass spectrometry, protein biochemistry, cell biology, genetics, proteomics, and molecular biology, we study the role of PTMs (primarily O-glycosylation) in a variety of pathophysiological processes including cancer, diabetes, viral infection, neurological disorders, and congenital muscular dystrophy. Our research is aimed at increasing our understanding of how increased functional diversity leads to finer control of biological processes. The hope is that by understanding the role of PTMs, we will not only more accurately describe fundamental biological processes but will also elucidate novel therapeutic targets in disease states where these processes have become dysregulated.
