Dr. Tracy L. Scheffler

Assistant Professor-Muscle Biology

Research Summary

The overall goal of Dr. Scheffler’s research is to optimize muscle growth, composition, and meat quality.  In particular, she is interested in how muscle metabolic phenotype and signaling pathways influence nutrient partitioning and growth of skeletal muscle, and their relation to whole body metabolism and health.  Dr. Scheffler incorporates various nutrition, genetic, and species models to manipulate fuel availability and/or signaling pathways in order to investigate mechanisms regulating muscle phenotype. Additionally, she is interested in the interaction between energy signaling, nutrient-sensing, and protein synthesis/degradation pathways, and their relationship to production parameters, such as lean gain and feed efficiency. Further, muscle metabolic properties and energy signaling pathways are highly relevant during the conversion of muscle to meat; thus, another focus is determining how these factors contribute to color, tenderness, and other traits that dictate economic value of meat products.
