Sarah Kirschner is a Ph.D. student at the Center for Translational Research in Aging and Longevity (CTRAL) in the Department of Health & Kinesiology, Texas A&M University. She obtained her Bachelor’s degree in Nutritional Sciences in November 2014 and her Master’s degree in Clinical Nutrition in January 2018 from the University of Hohenheim, Germany. She conducted her graduating research at CTRAL under the supervision of Drs. Nicolaas Deutz and Marielle Engelen. Her thesis focused on protein digestion and net anabolic response to a protein meal in the elderly and patients with Chronic Obstructive Pulmonary Disease (COPD) and Congestive Heart Failure, and on the development of a stable tracer method to measure short-chain fatty acid (SCFA) metabolism. In her doctoral research, Sarah will investigate SCFA and fiber metabolism in COPD patients as well as SCFA metabolism and flux measurements during sepsis in a pig model.
