My primary research interests lie in understanding the neurobiology of motivated behaviors. Specifically, I am interested in how motivated behaviors that occur as a part of an individual’s everyday life, such as social and reproductive behaviors, result in long-lasting changes in the brain that can influence the biological impact and future expression of those behaviors. In addition, I am interested in how experience with naturally-motivated behaviors can impact an animal’s vulnerability to abnormal motivated behaviors, such as drug addiction. To understand these complex brain-behavior relationships, I use Syrian hamsters as a model organism. My research takes a comprehensive technical approach, ranging from the cellular/molecular to the systems/behavioral levels of analysis.
