Research Interests

My lab is currently interested in studying the effect of sleep duration on energy balance as well as the impact of functional foods and ingredients on energy balance.  Energy balance is measured by assessing energy expenditure, using indirect calorimetry, doubly-labeled water, and actigraphy, and energy intake, via weighed laboratory measurements and taking the difference between the 2.  Alternatively, careful evaluation of a person’s change in body composition can yield information on his or her metabolic status and energy balance; a reduction in body weight and adipose tissue will indicate a negative energy balance.  Body composition measurements of choice in my laboratory are magnetic resonance imaging and dual energy X-ray absorptiometry.
