South Texas Veterans Health Care System (STVHCS)
Nicolas Musi, MD, Director, is a Physician-Scientist who received clinical training in Internal Medicine at the University of Miami-Jackson Memorial Medical Center. Dr. Musi then completed a clinical and research fellowship in Endocrinology and Metabolism at the Joslin Diabetes Center-Beth Israel Deaconess Medical Center and Harvard Medical School in 2001 after which he joined the Harvard faculty. Recruited to The University of Texas Health Science Center at San Antonio (UTHSCSA) * in 2003, he served as Associate Director for clinical research at the Texas Diabetes Institute and is the Director of the Barshop Institute for Longevity and Aging Studies *. Upon being named Director of the GRECC in 2010, Dr. Musi was also appointed Director of UTHSCSA Medical School’s Center for Healthy Aging *.
Dr. Musi’s research expertise is in aging, insulin resistance and exercise physiology. Dr. Musi has a robust research program in metabolic/endocrine gerontology, devoted to exploring the effects that aging has on numerous metabolic and cellular processes, and relevant to the patho-genesis of age-related diseases such as diabetes, obesity, and sarcopenia. He is principal investigator on two National Institutes of Health R01 (project) grants and a grant from the American Diabetes Association. Dr. Musi is the recipient of a Paul B. Beeson Career Development Award in Aging Research, co-sponsored by the National Institute on Aging (NIA) and the American Federation for Aging Research. An active educator and research mentor, he supervises clinical and research fellows, residents, and graduate students. Dr. Musi’s main clinical interests are (i) pathogenesis, prevention and treatment of diabetes in the elderly; (ii) molecular mechanisms underlying sarcopenia of aging; and (iii) effects of exercise on glucose and lipid metabolism at the whole-body and cellular levels.
Chih-Ko Yeh, BDS., PhD, Acting Associate Director for Research Dr. Yeh’s research is focused on studying the effect of aging on oral health, with a special emphasis on saliva and salivary gland biology/physiology. These studies include: 1) monitoring oral health/saliva function of aging, hypertensive, and diabetic stratified populations, as well as HIV infected patients, 2) exploring the pathogenesis of age-related oral and salivary gland diseases, and 3) salivary gland regeneration/repair with stem cells. Most recently, his laboratory has been involved in several translational studies developing saliva-based diagnostics for MI and cancer detection using nanotechnology and effective, long-term anti-fungal (specifically, anti-candida) denture materials. Dr. Yeh’s laboratory contains all necessary equipment and resources for performing modern chemistry, physiology and molecular and cell biology studies.
Sara E. Espinoza, MD, MSc, Associate Director for Clinical Programs, leads the GRECC clinical programs. Dr. Espinoza is a fellowship-trained, dual board-certified Internist and Geriatrician. She earned her medical degree in 2000 from the University of Virginia and completed her residency training at the University of Rochester Medical Center in 2003. She then completed a three-year clinical and research fellowship in geriatrics and gerontology at the Johns Hopkins Medical Institutions. Dr. Espinoza joined the San Antonio GRECC in 2006, and has since sustained an active research program investigating frailty. Dr. Espinoza is an active provider of clinical care as a G/EC geriatrician at the Audie L. Murphy Memorial VA Hospital. She is a funded clinical investigator whose research focuses on the epidemiology and pathophysiology of frailty. Dr. Espinoza is engaged in teaching through her clinical activities at the STVHCS, as well as in research education and mentorship of trainees at multiple levels in her role as Section Chief for Research with the Division of Geriatrics, Gerontology and Palliative Medicine in the Department of Medicine at The University of Texas Health Science Center at San Antonio (UTHSCSA) *
Jeanette Ross, MD, Acting Director for Education, is interested in integrating Geriatric Palliative Care content into educational programs at the undergraduate and graduate medical education levels. Her main interests include: advanced communication skills, goals of care, pain management and management of falls in elders. Her clinical activities are based at the Audie L. Murphy Veterans Administration Hospital, where she works in the Geriatrics and Palliative Care Consultation Service, and the Geriatrics Clinic. Dr. Ross is interested in using social media to enhance teaching and learning.
