Michael Delp, PhD
Dean & Betty M. Watts Professor
Upon completion of graduate work at the University of Georgia, where he earned a doctorate in exercise physiology and a Master of Arts degree in exercise physiology, Dr. Michael Delp served as the Alexander von Humboldt Research Fellow at the University of Konstanz in Konstanz, Germany, and was a postdoctoral fellow in the Department of Biomedical Sciences, College of Veterinary Medicine, at the University of Missouri.
Prior to coming to Florida State University, Delp was a Professor and Chair of the Department of Applied Physiology and Kinesiology at the University of Florida, a Professor and Vice Chair in the Division of Exercise Physiology at the West Virginia University School of Medicine, and a faculty member in the Department of Health and Kinesiology at Texas A&M University.
Dr. Michael Delp’s research is primarily focused on understanding the effects of physical activity on the cardiovascular system and, more specifically, the microcirculation. To accomplish this goal, his laboratory has used exercise training to investigate the effects of high levels of physical activity on cardiovascular function, while aging, microgravity (simulated and actual) and type II diabetes have been used as models where low levels of physical activity is a key component of the condition. According to the American Heart Association, physical inactivity is a major risk factor for developing coronary artery disease, stroke and peripheral vascular disorders. It also contributes to other risk factors, including obesity, high blood pressure, low levels of HDL cholesterol, and diabetes. Work from the Delp laboratory has focused on the full spectrum of physical activity on smooth muscle and endothelial cell function of resistance arteries, and how activity-related alterations in vasomotor function alters control of arterial pressure and tissue perfusion.
Specific areas include:
- The effects of aging and exercise training on vascular control mechanisms in skeletal muscle.
- The effects of actual and simulated microgravity on microvascular control mechanisms in the brain, splanchnic tissue and skeletal muscle, and how these alterations contribute to health risks associated with spaceflight.
- The possible coupling of diminished blood flow and microvascular endothelial function to bone loss associated with disuse, old age and type II diabetes.

Kirk Evanson, PhD
Dr. Kirk Evanson received his Ph.D. in Kinesiology from the University of Arkansas in 2011. Dr. Evanson was a postdoctoral fellow at the University of Tennessee Health Science Center (UTHSC) from 2011-2015. While at UTHSC, Dr. Evanson was a recipient of a National Institutes of Health (NIH/NHLBI) Ruth L. Kirschstein National Research Service Award (2012-2015).
Dr. Evanson’s research focus is on ion channel regulation of arterial contractility. Ion channels are specialized proteins that span cell membranes to provide passage for charged particles (ions). In excitable vascular smooth muscle, ion channels are primary regulators of cell membrane potential and arterial diameter, and ion channel dysfunction in vascular smooth muscle is associated with vascular disease. Dr. Evanson is interested in identifying novel ion channel proteins and mechanisms that could improve our understanding of vascular function in normal and pathophysiological conditions. Dr. Evanson uses a comprehensive approach to study vascular smooth muscle protein expression and function. Techniques include RT-PCR, Western blotting, surface biotinylation, patch-clamp

Dr. Ilich-Ernst’s research is comprehensive and multifaceted and includes:
with nutritional intervention in human subjects incorporating behavioral modification and modes of physical activity for augmentation of bone and body composition (muscle and fat tissues). In 2012, Dr. Ilich-Ernst has identified a triad incorporating bone loss, muscle loss and adipose tissue expansion in older individuals and termed it “osteosarcopenic obesity syndrome”. Recently, she started investigating the newly discovered hormone, irisin, in connection with brown- and beige-fat activation.
OUTREACH TO UNDERSERVED COMMUNITIES
for education and health promotion interventions to foster obesity prevention, improvement in cardiovascular risk factors and overall healthier lifestyle.
in animal models with feeding studies and investigating the bioavailability of calcium, magnesium, and zinc and their competitive interaction during absorptive processes. This includes metabolic and balance studies of those minerals in human subjects, and in vitro and in vivo experiments in animals.
investigating nutritional influences on mesenchymal stem cell differentiation into osteoblasts (bone forming cells) and adipocytes (fat cells) lineages and cross-talk with myocytes (muscle cells). Insight into the pathways and nature of the metabolites involved will lead to better understanding and regulation of the overall functioning of bone, adipose, and muscle tissues and their inter-connective trajectories.
Dr. Ilich Ernst has started two new projects:
- Determining the prevalence of osteosarcopenic obesity in women of a wide age range and individuals with other chronic diseases (e.g. cancer, diabetes) and its influence on functional abilities and metabolic profile. Osteosarcopenic obesity is a new concept, fashioned by Dr. Ilich-Ernst in 2012, and includes low bone and muscle mass and strength (osteoporosis and sarcopenia) coexistent with obesity.
- Investigating the irisin-brown-fat axis in humans and animal models. Irisin is a newly discovered signaling protein released by muscle cells upon exercise. Irisin activates thermogenic processes in white adipose tissue causing its “browning” and leads to increased mitochondrial biogenesis, heat production and energy expenditure. Delineating functions of this messenger system in humans will determine whether irisin and some other related factors could be targets for therapeutic approaches for conditions caused by excess energy consumption, such as obesity and diabetes.

Maria Spicer, PhD, RD, LDN
Dr. Spicer has been a registered dietitian since 1985 and has had clinical nutrition experiences in pediatric surgery, long term care and OB-GYN. Her research focuses on the relationship of factors that cause obesity and insulin resistance, and, in the treatment of metabolic syndrome using complementary and alternative approaches to therapy and the prevention of chronic diseases such as diabetes, kidney and cardiovascular disease. In addition to research and teaching graduate courses in dietetics, Dr. Spicer is the Director of the Graduate Dietetic Internship Program which is designed to provide supervised experiences in community, clinical and management dietetics which prepare graduate students for the registration exam of the Commission on Dietetic Registration and for practice in the diverse field of nutrition. The internship experiences include rotations in nutrition research, health promotion and sports dietetics.
Dr. Spicer’s research focuses on the effects of lifestyle practices on health and the development chronic diseases. This includes the detrimental effect of malnutrition and the lack of physical activity on body weight and the consequent health problems resulting from insulin resistance due to excess body weight. Overweight youth are suffering from chronic diseases that young people rarely experienced decades ago. The early detection of insulin resistance in children and adolescents should be a trigger for instituting early lifestyle interventions that promote positive lifelong changes in health behavior resulting in the prevention of chronic disease especially in at risk populations. Her research has shown that chronic high fat intake during the growing period results in the greater accumulation of body fat and hypersecretion of insulin in response to a glucose challenge in rats especially during the prepubertal period. Dr. Spicer's research team found that C-peptide concentrations were the single, most sensitive and specific indicator of insulin resistance in overweight Native American children compared to HOMA-IR and earlier than fasting glucose would indicate. Measuring C-peptide is less invasive, less time consuming, less complex and less expensive than glucose tolerance tests or glucose clamps. Thus, she is exploring the predictive ability and accuracy of C-peptide concentrations in detecting insulin resistance in overweight children with the ultimate goal of promoting lifelong healthy habits and a better quality of life.
