Current Research

My principal line of research involves the physiological and environmental variables that affect food intake and may produce obesity. Using a mouse model, we are focusing on economic factors by varying the cost of access to food, when food is available, and the effect of voluntary exercise. Using genetically obese mice, or mice made obese by a high fat diet, we are able to examine the effectiveness of different weight loss regimens. Using serotonergic receptor subtype-specific drugs we are assessing the short and long-term efficacy of anorectics in structured feeding environments.
Some aspects of food intake are similar to addiction. Therefore, additional studies in my lab are investigating alcohol or nicotine intake, in rats, and their interaction with food consumption. For the alcohol work, we developed a novel gelatin-based alcohol matrix that allows simultaneous manipulation of carbohydrate calories, and operant delivery. For nicotine, rats either self-administer intravenously or receive nicotine infusions, in extended access protocols with patterns that emulates the pattern of smoking by typical heavy smokers.
