Background and Interests
I've always found it fascinating that small molecules such as alcohol and morphine can come to control complex behaviors like drinking and elicit addictive behaviors. I worked as a technician in Harriet deWit's human behavioral psychopharmacology laboratory at the University of Chicago; where I learned that an individual's response to an abused drug depends on a number of factors, ranging from social to biological. I became very interested in the biological and genetic aspects of addiction, but found that many of my questions could not be answered using human subjects. When I asked Dr. deWit her thoughts, she said "You should go to OHSU for graduate school, they have excellent faculty that is focused on addiction yet will provide you with broad neuroscience training". So I did that. Through my graduate studies, I became interested in the idea that abused drugs act through some neurochemical pathways, especially those involving the neurotransmitters dopamine and glutamate. My dissertation work with Tamara Phillips involved testing genetically distinct populations of mice for their responses to alcohol, and whether these responses were related to alcohol's effects on glutamaterigc and dopaminergic systems. The great thing about the highly interactive nature of the Department of Behavioral Neuroscience is that its trainees are kept up to date with research in their own and related fields. For example, I learned through courses and seminars that dopamine and glutamate systems play important roles in reinforcement learning, and that drugs of abuse may cause addictive disorders by hijacking these systems, suggesting that drug addiction could be thought of, in some instances, as a dopamine-dependent associative learning disorder. This, to me, is an intriguing idea, and I've dedicated my career to studying the role of dopamine in responding to drug- and motivationally-relevant stimuli. The techniques I've used have been as simple as measuring locomotion in mice and as complex as using patch clamp electrophysiology in brain slices. Currently, my laboratory at SUNY Buffalo studies how neurons within the limbic system encode stimuli that predict food and drug reward, and how this encoding related to the propensity to engage in addiction-related behaviors.
