My laboratory investigates how metabolism and the brain adapt in response to a variety of interventions to diet and physical activity. We perform experiments in both humans and rodents to better understand the complex mechanisms regulating macronutrient metabolism, body composition, and energy expenditure. A unique aspect of our laboratory involves the development of mathematical models to quantitatively describe, explain, integrate, and predict our experimental results.

Research in Plain Language
My laboratory studies the regulation of body weight and metabolism—the processes through which food is converted into the energy. We perform experiments in both humans and rodents to better understand the complex mechanisms that control
- metabolism of macronutrients—proteins, fats, and carbohydrates;
- food choice and eating behavior;
- body weight and composition; and
- energy expenditure, which is the amount of calories used to maintain life and perform physical work.
A unique aspect of our research group is that we develop mathematical models to describe, explain, integrate, and predict the results of our experiments.
