Biographical Info

Dr. Stapleton is an Assistant Professor in the Rutgers University, Ernest Mario School of Pharmacy, Department of Pharmacology and Toxicology, and the Joint Graduate Program in Toxicology. She received her B.S. in Biology and Athletic Training from State University of New York (SUNY) College at Cortland, a M.S.Ed. in Kinesiology from Southern Illinois University at Edwardsville, and a Ph.D. in Exercise Physiology from West Virginia University. She completed her postdoctoral training within the Department of Physiology and Pharmacology at West Virginia University.

Research Areas

The microcirculation branch of the cardiovascular system encompasses the arterioles, capillaries, and venules within an organ or tissue of interest. These highly active vessels serve to maintain homeostasis by regulating blood flow and tissue perfusion, thus providing nutrients and removing waste. Central to proper reactivity is the health and function of the endothelium, a single cell layer lining the vasculature. The Stapleton laboratory investigates the microvascular perturbations associated with normal physiological challenges (exercise or pregnancy), disease, and exposures to environmental and/or occupational xenobiotics.

Using engineered nanomaterials, studies focus on the question: how can something we inhale affect the cardiovascular system? Recently, her research group has investigated non-traditional models of exposure by incorporating reproductive toxicology. These studies focus on exposures during pregnancy leading to the development of a hostile gestational environment identified through microvascular evaluations of the mother. These prenatal exposures impact fetal development and may predispose future generations to cardiovascular aberrations. The Stapleton laboratory is funded by NIH K99ES024783.
