Our research interests include human nutrition and exercise studies on protein, carbohydrate and energy metabolism, dietary protein and energy requirements, body composition, obesity, weight loss, muscle strength, and muscle function with special emphasis on aging. We are also interested in how nutrition, exercise, and aging impact appetite and ingestive behaviors. Our research suggests that older people who habitually consume the Recommended Dietary Allowance for protein experience subtle declines in skeletel muscle size. Thus we seek to find the optimal protein intake for older and elderly people to consume. Our research also focuses on how protein metabolism, body composition, and glucose metabolism change in older people with changes in protein intake, body weight, and exercise (especially strength training). We are also interested in evaluating the effectiveness of compounds that are promoted to have ergogenic properties (e.g. whey protein). 

Our research includes the use of traditional metabolic balance techniques (with strict dietary control possible in a metabolic research kitchen), stable isotope infusion techniques (to measure in vivo amino acid turnover and incorporation into muscle tissues), body composition (plethysmography, dual x-ray absorptiometry, deuterium oxide dilution, magnetic resonance imaging), the muscle biopsy technique (to obtain small samples of human skeletal muscle), and indirect calorimetry (to measure resting and exercise energy expenditure). We also highly value collaboration within and outside of Purdue to expand our interests, expertise, and research capabilities.

NUTR 48800 Topics in Nutrition, Fitness, and Health: This course is designed to provide juniors and seniors in the nutrition, fitness, and health curriculum with a review of the current literature as it relates to their major. Specific information from previous courses in separate disciplines will be integrated to study the interrelationships between nutrition and exercise and their impact on physical performance and health. Concepts combining nutritional sciences and exercise physiology will be presented, and controversies in the current literature will be discussed.
