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.
We are also interested in evaluating the effectiveness of compounds that are promoted to have ergogenic properties. The potential importance of the physical form of food (e.g. liquid versus solid) on appetite, ingestive behaviors, energy balance, and body weight control is also of great interest to our research team.
Areas of Expertise:
- Dr. Campbell specializes in conducting randomized controlled trials with prescribed eating patterns with human adult participants.
- Current research emphasizes studying the effects of various agricultural commodities (e.g., mushrooms, red meats, plant-based protein foods, poultry, and dairy products) on indices of human health.
- Dr. Campbell's research group has expertise conducting systematic reviews and meta-analyses of literature.

His current research focuses on assessing the effects healthy eating patterns and protein-rich foods on nutri-metabolomics, cardiometabolic disease risk factors, indices of well-being. Dr. Campbell, and colleagues also study influences of dietary protein source, quantity, and within-day patterning on body composition (including muscle and bone) responses to anabolic and catabolic stimuli (exercise training and dietary energy restriction, respectively, and dietary protein needs of older adults.
