Allen, Ronald: Muscle biology; growth and repair of skeletal muscle; muscle stem cells; satellite cell activation
Baumgard, Lance: Nutritional Physiology Research focus will be on improving efficiency of animal production and to better understand how nutrient utilization is regulated. Of special interest is how homeostatic and homeorhetic systems control nutrient partitioning to support different physiological states. Areas of research will involve nutritional, biochemical, molecular, and endocrine aspects of metabolism. Lactation: Research will concentrate on mechanisms regulating milk synthesis and production of milk components. This will involve studying the process of how milk fat is synthesized and how environmental factors, including nutrition and ambient temperature, regulate both the yield and composition of milk fat. Goals are to discover techniques to manipulate milk fat production to improve animal performance and well-being and improve the healthfulness of dairy products. Continued efforts will be made to identify the biological mechanisms by which selection mediates increased milk yield and to understand the variation and improve the efficiency of milk production. Growth: Research will focus on understanding lipid metabolism during growth. This will involve studying the process of how nutrients are coordinated and partitioned between accretion of lean and adipose tissue. Efforts will be made to manipulate lipid metabolism to improve efficiency and healthfulness of animal products
Burd, Randy: Current Research Interests: Current research interests in our laboratory focus on improving tumor radiation response through the use of biological response modifiers that alter tumor cell function, metabolism, cytokine stimulation and prostaglandin production, and affect aspects of tumor development, growth and treatment response. These include pharmaceutical drugs that are designed to specifically target tumors, bioactive nutritional components such as bioflavonoids, and compounds that regulate tumor glucose metabolism
Collier, Robert: Environmental physiology, environmental effects on gene expression in domesticated animals
Going, Scott: Dr. Going is an expert in models and methods for assessment of changes in body composition during growth and aging. He is also an expert in physical activity and fitness assessment and the design of exercise interventions. He is currently researching the effects of chronic exercise and nutritional factors on bone development in adolescent girls; nutrition, exercise and hormone replacement on bone in postmenopausal women; the effects of muscle loss on bone loss and hip geometry in older women; and diet and exercise for pediatric obesity prevention and weight loss in women.
Hartshorne, David: Research goals are to gain a better understanding of the contractile or motile, mechanism in smooth muscle and in non-muscle cells. This involves investigations of the proteins myosin, myosin-light-chain kinase and myosin-light-chain phosphatase. Another major emphasis is to elucidate the role of phosphorylation in cytoskeletal structure. The latter utilizes bacterial toxins, that occur as contaminants in food and drinking water, and chemicals in common use as herbicides and insecticides.
Henriksen, Erik: Our research group is interested in the regulation of carbohydrate and protein metabolism in skeletal muscle by endocrine factors and contractile activity, particularly in the context of insulin resistance and type 2 diabetes
Houtkooper, Linda: Investigation of the roles of nutritional status and physical activity in disease prevention, optimal health promotion, and sport performance.
