Dr. Simon received her Ph.D. in endocrine physiology with the support of an Indian Council of Agricultural Research fellowship and did her postdoctoral training at the College of Veterinary Medicine, University of Illinois at Urbana Champaign in stem cell/endocrine physiology. She was an Assistant Professor in the Department of Biomedical Sciences at the College of Veterinary Medicine, Tuskegee University from 2010-2013. She also held an adjunct faculty position, Department of Pathology, School of Medicine at the University of Alabama at Birmingham from 2012-2013. She joined the Department of Physiology at LSUHSC, NO in July 2013.

Research Interests

Research in our laboratory focuses on mechanisms that regulate proliferation and differentiation of stem cells. Using animal models, we are studying epigenomic interactions that impair stem cell function contributing to dysregulated repair, regeneration and function. We are specifically interested in the dysregulation of skeletal muscle stem cell signaling that alters the fate of these cells in insults including alcohol use, HIV and disuse muscle atrophy. Our laboratory utilizes in vivo approaches, including models of alcohol administration and disuse atrophy; cell culture systems; and a wide array of molecular biology techniques to study genetic and epigenetic changes that contribute to dysfunction. Our ultimate goal is to develop epigenomic-targeted therapeutic and lifestyle interventions that improve muscle function and quality of life in aging or chronic diseases. The lab has also developed close collaborations within the department and at LSUHSC to investigate epigenomic mechanisms in metabolic dysregulation, and HIV disease
