Dr. Michelle Duffourc, Director

Dr. Michelle M. Duffourc is a neuroscience researcher and teacher. Her laboratory has two primary interests: 1) understanding the molecular basis of hereditary blinding disorders and 2) determining the factors that control gene expression in the retina. Her research efforts have earned her a National Research Service Award from the National Eye Institute and a Pediatric Ophthalmology Fellowship from the Knights Templar Eye Foundation. She is a member of the American Society for Pharmacology and Experimental Therapeutics, Sigma Xi, and the Association for Research in Vision and Ophthalmology.

In addition to her research program, Dr. Duffourc is an experienced teacher of molecular biology techniques. Besides training undergraduate, medical and graduate students, she has taught classes in DNA sequencing and served as a faculty member in ETSU’s acclaimed Methods in Molecular Biology Workshop. Her teaching efforts have resulted in her being honored with the Genesis Award for Professor of the Year from the Biomedical Graduate Program, the James H. Quillen College of Medicine Dean's Distinguished Teaching Award in Basic Medical Sciences, and being named to Who's Who Among America's Teachers.

Dr. Duffourc received her doctoral degree in Basic Medical Sciences with a specialization in Pharmacology from the University of South Alabama School of Medicine and completed a postdoctoral fellowship in Biochemistry & Molecular Biology from the same institution. In 1998 she joined the faculty at the James H. Quillen College of Medicine at East Tennessee State University where she currently is an Associate Professor of Biomedical Sciences and Adjunct Associate Professor of Pathology and Biological Sciences.
