Lawrence R. Aaronson, Ph.D.
Professor of Biology

A native Floridian, I earned a B.S. degree in Biological Sciences from Florida State University in 1979. In 1984 I received a Ph.D. in Microbiology from Rutgers University where I studied the regulation of membrane fluidity during cold adaptation in fungi in the laboratory of Dr. Charles Martin. Later, I studied the biogenesis of the fungal plasma membrane proton pump as a postdoctoral fellow in the Department of Human Genetics at Yale School of Medicine with Dr. Carolyn Slayman. I joined the faculty of UticaCollege in 1987, and teach Principles of Microbiology, Molecular Biology, Immunology, and Virology, among other courses.
An advocate for undergraduate research, I presently serve as a Biology Councilor in the Council on Undergraduate Research and am a member of the Committee on Undergraduate Education of the American Society for Microbiology where I am leading the new Undergraduate Teaching Fellowship Program. I was honored at UC in 1996 with the Crisafulli Distinguished Teaching Award and with the Harold T. Clark Award for Research in 1997. In 2007, I received the American Society for Microbiology/Carski Foundation Distinguished Undergraduate Teaching Award. (http://www.asm.org/Academy/index.asp?bid=39527)
My hobbies include reading biomedical thrillers, rose gardening, making and throwing boomerangs, and all things Star Trek.
Research Interests and Research in Progress
My current research interests are focused on the study of natural antifungal defenses in animal skin. For the past 15 years my lab group has concentrated on the study of the antifungal properties of sphingolipids, which may create a natural antifungal barrier in the skin. These studies may identify new agents to combat deadly infections by fungal pathogens. Other ongoing projects include an investigation of the antifungal bacterial flora of red-backed salamanders, and the biodiversity of bacteria in PCB-contaminated sediments of the Utica Marsh. New projects include induction of swarming activity in Bacillus cereus, and photoregulation of melanin production in Pseudomonas sp. UC17F4.

Opportunity for Student Research
Over the past 23 years, as many as 60 Utica College students and 18 students from local high schools have worked on research projects in my lab. Many of these students have presented papers at national scientific meetings, and have received grants and fellowships from the American Society of Microbiology, The Microscopy Society of America and Sigma Xi to support their research. Some of the students from my research group have gone on to earn graduate degrees from institutions as Yale, George Washington University, Penn State, University of Pittsburgh, University of Maryland, University of Rochester, University of Alabama – Birmingham, Mayo School of Medicine and Howard University.
