Biography
Dr. A. Timothy Royappa, Professor of Chemistry, is in UWF’s Distinguished Teaching Hall of Fame. To be accepted into the Hall of Fame, a teacher must win the UWF Distinguished Teaching Award three times. Dr. Royappa has won the UWF Faculty Award for Excellence in Teaching and Advising six times. He has a Ph.D. in Physical Chemistry from Massachusetts Institute of Technology and a B.S. in Chemistry from Indiana University. His teaching responsibilities include classes in physical chemistry, polymer science, and inorganic synthesis.
Dr. Royappa’s current research focuses on the synthesis and characterization of copper(I) complexes for applications in microelectronics manufacture, pharmaceutical science, and nanoparticle synthesis. He is also interested in the elucidation of molecular structure and intermolecular interactions by crystallography. His findings have been published in numerous peer-reviewed journals such as Nature Chemistry, Journal of the American Chemical Society, Organometallics and Polyhedron. Dr. Royappa has won the Distinction in Faculty Research and Scholarly Activities Award and the Senior Career Faculty Excellence in Undergraduate Research Mentoring Award at UWF. He has been a scientific consultant to several companies as well as the Florida Department of Education.
