Environmental Influences on Health & Disease
(605) 312-6405

The Vitiello laboratory works to identify and define the molecular interface between environmental toxins and biological systems, influencing tissue development, homeostasis, and disease pathogenesis. Research is targeted at understanding how toxins alter redox signaling and molecular networks via cysteine oxidation. The laboratory uses a variety of genetic, molecular, proteomic, and cellular approaches to determine the role of redox signaling during development and disease in response to oxidative perturbations.

 Dr. Vitiello graduated from Lafayette College with a BS in Biology and obtained a PhD in Toxicology in the Department of Environmental Medicine at the University of Rochester School of Medicine and Dentistry. Peter continued as a postdoctoral fellow in the Department of Pediatrics at the University of Rochester School of Medicine and Dentistry. Currently, he is an Assistant Scientist in the Environmental Influences on Health & Disease Group at Sanford Research and Assistant Professor of Pediatrics at the University of South Dakota Sanford School of Medicine.
