Professor of Kinesiology
Dr. Alexander utilizes in vivo and in vitro approaches using the human cutaneous circulation to examine the underlying signaling mechanisms mediating microvascular dysfunction with primary human aging, hypercholesterolemia, and essential hypertension.
Professor of Bioengineering
Fundamental molecular mechanisms by which vascular endothelial cells sense the forces from flowing blood and transduce this mechanical information into adjustments of cell and tissue biology.
Elizabeth Fenton Susman Professor of Biobehavioral Health
The causes of chronic sleep deficiency in the workplace, home, and society; the health consequences of chronic sleep deficiency, especially cardiometabolic outcomes, and the physiologic and social mechanisms by which these outcomes arise. Successful aging is a central focus of this work. Ongoing interdisciplinary human studies involve sleep loss, aging, and insomnia, as well as health disparities.
Director of the Center for Molecular Immunology and Infectious Disease; Distinguished Professor of Molecular Immunology
Understanding the working of the immune system. Utilizing animal models of several human diseases including enteric infections and inflammatory bowel disease to determine the cellular targets and molecular signals by which dietary components regulate immunity.
Chair, Intercollege Graduate Degree Program in Neuroscience; Associate Professor of Biobehavioral Health
Development of temperament/personality; relationship of temperament and social status to stress and health; individual differences in stress and health in the natural environment.
Huck Early Career Chair in Neurobiology & Neural Engineering; Assistant Professor of Biology and Biomedical Engineering; Associate Director for Postdoctoral Training and Leadership, Center for Neural Engineering
Investigation of peptidergic transmission throughout the brain, using cell-specific and pathway-specific manipulations to understand how peptides alter neuronal signaling and behavior, particularly in the context of stress and drug use.
Distinguished Professor of Kinesiology
Women's health and Physical Activity, Endocrinology of the Female Athlete, Effects of Exercise on the Menstrual Cycle, Female Athlete Triad (Eating disorders, amenorrhea and osteoporosis), Eating Behaviors, Food Intake, and Exercise, Luteal Phase Defects and Amenorrhea, Bone Health and Osteoporosis in Female Athletes, and Energy Deficiency and Bone Health.

Ovarian physiology. Role of SMAD-mediated signaling in follicular and female germ cell (oocyte) development.
Dr. Frances Keesler Graham Early Career Professor; Assistant Professor of Veterinary and Biomedical Sciences
Building tools to elucidate the complex genetic and environmental underpinnings of human disease. Integrating genetic (genotype, sequence, structural variation) and exposure (derived from surveys and metabolomics methods) big data to predict disease status.
Associate Professor of Nutritional Physiology
Investigation of dietary factors that modify ruminal fatty acid biohydrogenation, regulation of synthesis of milk components, and basic regulation of lipid synthesis with the continual goal of developing feeding strategies to improve the efficiency and performance of dairy cows
Emphasis Area Representative, Molecular Toxicology; Assistant Professor of Veterinary and Biomedical Sciences
Development of new metabolomics tools for chemical and biological characterization of complex systems. Discovery of new natural products from plants and microorganisms with novel bioactivity against pathogenic fungi and neglected tropical diseases. Bioanalytical techniques to probe the mechanism of action and basic biology of these target organisms. Ethnobotany and indigenous knowledge surrounding plant-based medicine.
Professor of Biobehavioral Health
Biobehavioral effects of stress on drug abuse; sex differences in neuroendocrine and behavioral stress responses; nicotine regulation of stress reactivity.
