Professor OF BIOLOGICAL SCIENCES Medical Technology Program Coordinator
With my background in animal physiology and signal transduction in protozoa, I have
always had an interest in cellular communication and interactions. In my current role
as a microbiologist, I have become increasingly fascinated with the versatility of
microorganisms, and truly enjoy teaching and research in this discipline. The immensely
positive impact of bacteria and other microbes is often underappreciated amidst the
many news stories of disease outbreaks. My current research focuses on ways that bacteria
utilize pigments to their advantage, as well as means of oxidative stress defense.
Other areas of research interest include contamination of water coolers and fiber
breakdown by microbes.
