Dr. Mike Hambourger, Department of Chemistry
- B.S. Biology, Appalachian State University
- Ph.D. Chemistry, Arizona State University
Dr. Hambourger is an Assistant Professor of Chemistry at Appalachian State University, where he enjoys his role as an educator and scientist. Following receipt of his B.S. in 2001, he served as a Peace Corps volunteer in Morocco, promoting alternative energy technologies. In 2008, Dr. Hambourger received his Ph.D. in Chemistry, followed by one year of post-doctoral experience at Arizona State University. Dr. Hambourger joined the faculty of Appalachian State University in 2009. His research interests pertain to the use of sunlight to meet future energy demands. Within the Department of Chemistry, Dr. Hambourger is exploring the surface immobilization of cobalt-based electrocatalysts for the interconversion of electrical and chemical energy, as well as related system for photochemical energy transduction. Through collaboration with faculty in the Departments of Technology and Biology at Appalachian State University, Dr. Hambourger also is pursuing biological methods of producing fuels and remediating waste.
