Short Professional Biography

Dr. Watt earned a B.S. in technical writing prior to completing a dual B.S./M.S. program in chemistry at Carnegie Mellon University.  His M.S. thesis, under the guidance of Dr. Bruce Armitage, described the synthesis of cyanine dyes and their nucleic acid binding properties.  In 2007, Dr. Watt earned a Ph.D. from the School of Chemistry and Biochemistry at the Georgia Institute of Technology.  His dissertation research, with Dr. Donald Doyle, examined how engineered mutations in nuclear receptors influence protein-ligand binding affinity and specificity, the self-association of the receptors, protein stability, and the overall intracellular activity of the proteins.  Dr. Watt then moved to the University of Michigan in Ann Arbor as a postdoctoral research associate in the lab of Dr. Carol Fierke.  His work there included assaying metal-dependent small molecule fluorescence, disrupting cellular metal homeostasis with toxic metals, analyzing the substrates of enzymes involved in post-translational modifications, and teaching undergraduate physical chemistry.  In 2010, Dr. Watt moved to Xavier University of Louisiana as a faculty member in the Department of Chemistry.

 

Research Interest

Dr. Watt's research activities focus on molecular recognition in biochemical systems.  He is currently researching how a small number of lysine deacetylases (KDACs, also known as histone deacetylases or HDACs) distinguish between the thousands of intracellular proteins that could serve as reaction substrates.  Acetylation of lysine is one of the most common post-translation modifications of proteins, and the acetylation/deacetylation cycle has central roles in gene expression, regulation of intracellular processes, and development of cancers.  To characterize KDAC substrate binding, Dr. Watt uses spectroscopy, enzyme kinetics, molecular biology, statistical models, and molecular modeling.
