Peter A. White

Associate Professor, Natural Sciences
(603) 526-3681 |

Joined the faculty in 2001. Received B.S. from University of Massachusetts-Dartmouth, Ph.D. from Indiana State University. Teaching interests include physiology, cellular pathophysiology, cellular biology and molecular biology. Professor White's research interests focus on the cellular and molecular events which characterize acute renal (kidney) failure. Specifically, the alterations to the cell membrane and the underlying actin cytoskeleton of renal proximal tubular cells in response to ATP-depletion. He is also interested in science education and is a member of the Association of College and University Biology Educators.
