Description of Research

Interestingly, many people experiment with drugs, but only a fraction of users become compulsive drug takers. I am interested in understanding individual difference traits that contribute to compulsive drug taking. Novelty and sensation seeking are traits identified in both humans and rodents that contribute to self-administration and compulsive drug taking. Yet, it is unclear whether high novel seeking rodents are more or less sensitive to psychomotor stimulants. Wouldn’t it be great if the animals could tell us!?!

Ultrasonic vocalizations (USV) are a real-time measure of affective and motivational states in rodents, especially under the influence of psychomotor stimulants. Rats can be bred to be high and low USV callers, suggesting USV could reveal differences in sensitivity between high and low vocalizing animals. My current research focuses on determining the relationship between novelty and USVs in an effort to predict amphetamine-induced drug response in rodents.
