Jon D. Piganelli, PhD
- Associate Professor of Surgery
After graduation from the Department of Microbiology at Oregon State University, Piganelli moved on to postdoctoral training at the Barbara Davis Center for Childhood Diabetes and the Department of Immunology at the University of Colorado School of Medicine. Where he focused his research and training in cellular immunology, more specifically on understanding why the immune system recognizes the cells responsible for producing insulin, islet beta cells, as foreign, leading to type 1 diabetes.
His training further encompasses the role of free radical signaling in modulation of immune function. Piganelli has also taught both graduate and medical students for the school of medicine throughout his tenure as well as serving on over 75 thesis committees both nationally and internationally. He is also involved heavily in recruiting potential graduate students to the interdisciplinary biomedical graduate program at the university. As a minority investigator he has been very active in recruiting and attending McNair scholars and the Society for the Advancement of Chicanos/Hispanics and Native Americans in Science recruitment meetings.
