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.

Agata McNew is a Research Associate at the Center for Translational Research in Aging&Longevity in the Department of Health & Kinesiology, Texas A&M University. She studied Biotechnology at West Pomeranian University of Technology in Szczecin, Poland, where she obtained her Master of Science in Engineering in 2010. After graduation, she completed post-diploma studies from Human Nutrition and Health Promotion at the same university and then registered for a Ph.D. degree conferment procedure at Faculty of Agronomy and Bioengineering, Poznań University of Life Sciences. Her thesis is focused on identification of quantitative trait loci (QTL) for reproductive performance of Sus scrofa domestica (domestic pig) and molecular analysis of candidate genes for those traits. In her current work, Agata’s research interest encompasses genomic and metabolic impact of nutrition in animal and human models with emphasis on energy metabolism in obesity.

Dr. Ruebush is a Research Associate at the Center for Translational Research in Aging & Longevity in the Department of Health & Kinesiology, Texas A&M University. She completed her BS and MS in Chemistry at Arizona State University and Texas A&M University, respectively. Her PhD in Curriculum and Instruction, completed in 2012,  focused on policy, professional development of high science school teachers, and student science achievement in Texas (dissertation title: Identifying patterns of relationships between professional development and professional culture with Texas high school science teachers and students). Prior to joining the group, Dr. Ruebush worked in the Research Compliance office at TAMU. Dr. Ruebush will be coordinating education efforts for CTRAL and assisting with regulatory compliance.

Clayton Cruthirds, MS is a Ph.D student in the Center for Translational Research in Aging & Longevity of the Department of Health & Kinesiology, Texas A&M University. He studied biology at the University of Missouri and obtained his Bachelor’s degree in May 2013. As part of his education he performed research for two years under Dr. Frank Booth in the Department of Biomedical sciences. Dr. Booth’s lab uses a rat colony that is selectively bred for either high or low wheel running in order to study the effects of exercise on various physiological systems. His projects ranged from quantifying muscle mRNA expression after chronic exercise training to the vasodilation response of an oral ATP supplement. These projects, among others, were performed under the supervision of Drs. Mike Roberts and Joe Company at the University of Missouri.

After his graduation from the University of Missouri he joined the research group of Dr. Tim Lightfoot at Texas A&M University as a master’s student. During his two years in this lab he worked with mice looking into the genetic basis for physical activity. His thesis project focused on the effect of housing density and wheel number on daily running in SENCAR mice. That is, how would housing multiple mice and multiple wheels in the same cage alter distance, time, and speed ran over a six month period. Click here to read more about Clayton Cruthirds.
