Research Interests

My research program is focused on understanding the endocrine-based regulation of physiological and metabolic function of skeletal muscle.  My lab employs an integrative experimental approach, in which we use cell culture and animal models to define mechanisms that we then work to translate to the human.  Specifically, we have developed skeletal muscle specific-inducible BRCA1 and ER-alpha knock out mice and the ability to ablate BRCA1 or ER-alpha expression in cultured human myotubes through shRNA delivered via AV virus approach. This integrative approach allows us to examine the same loss-of function approach using in vivo animal models and cultured myotubes from humans. My lab has developed a number of techniques that allow us to measure or image metabolic and physiological changes in whole muscle or cultured adult single muscle fibers.  The ability to integrate these approaches gives us a significant experimental advantage because it allows us to make reductionist based measures in a whole muscle or a single muscle cell that retains a true adult functional phenotype.   For example, we have recently developed and/or optimized approaches to measure force, mitochondrial function, deliver cDNA, image lipid droplets or other organelles, and employ co-culture approaches in these single muscle fibers.
