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
Bernstein, Harris: Colon cancer
Chen, Qin: Molecular mechanisms of oxidative injury and adaptation; stress signal transduction pathways; genomics and proteomics of stress response; cytoprotective agents
Dornhaus, Anna: Organization in groups, how collective behaviors emerge from the actions and interactions of individuals, is the main interest of Anna Dornhaus. As model systems she studies social insect colonies (bumble bees, honey bees and ants) in the laboratory and in the field, as well as using mathematical and individual-based modeling approaches. She investigates mechanisms of coordination in foraging, collective decision-making, task allocation and division of labor. Her recent work has included the role of communication in the allocation of foragers to food sources; the evolution of different recruitment systems in different species of bees, and how ecology shapes these recruitment systems; house hunting strategies in ants; speed-accuracy trade offs in decision-making; and whether different group sizes necessitate different organizational strategies. Please check my homepage for details on individual projects.
Farley, Becky: clinical neuroscience, rehabilitation science, motor control and motor learning, biofeedback technology, exercise science, activity-dependent plasticity, dual task function, gait, arm movements, handwriting
Ferriere, Regis: Interplay between adaptive trait evolution and ecological interactions. Mathematical foundations of adaptive dynamics modelling. Empirical testing using clonal microarthropods and lizards.
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.
Hoyer, Patricia: Female reproduction: mechanisms of hormone action; regulation of steroidogenesis
