Sarah  Pearce    Research Physiologist (Animals) /ARSUserFiles/55822/SarahPearce.jpg
 Dr. Pearce acts as a Research Animal Physiologist within the Agroecosystems Management Research Unit at NLAE. The Research is conducted under the ARS National Research Program 101-Food Animal Production. The goals of Dr. Pearce’s personal research are to determine the impact of nutrition programs (e.g., phytochemicals), external environmental stressors (e.g., heat stress), and internal physiological stressors (e.g., pathogens) on basic and applied mechanisms in the gastrointestinal tract necessary to maintain or improve animal productivity, reduce oxidative stress, and maintain the structural integrity of the gastrointestinal tract.
