Behavioral and Molecular Neuroscience


Neuropsychiatric disorders, including addiction, are public enemy number one in North America, contributing twice the disease burden of even cardiovascular disease or cancer and costing the USA nearly 600 billion dollars per year. Current treatments are extremely limited, with relapse to alcohol and/or drugs common in individuals even after years of abstinence. Thus, there is an urgent need to develop novel, effective therapeutic strategies for alcohol and drug use disorders.

A large body of evidence suggests that circadian rhythm and sleep disruption may play a central role in drug abuse and relapse. Research in my lab aims to characterize this role in rodent models using a combination of cutting-edge techniques in the areas of molecular biology, neurochemistry, pharmacology, and behavioral neuroscience. My ultimate goals are to elucidate the mechanisms involved in the pathophysiology of addiction and related psychiatric disorders and to translate my research into clinical practice.

Current Projects

  1. Disruption of mammalian circadian timing by alcohol and stimulant
  2. Brain region-specific roles of clock genes in addictive behavior
  3. The role of reward circuitry in circadian timing and sleep
  4. The role of the circadian system in mood disorders

Student Training

I feel strongly that students get the best scientific training when they can participate in innovative research that answers new questions. Students in my lab will learn to apply methodology ranging from the gene to the behavioral levels, including real-time PCR, in vivo microdialysis, confocal microscopy, and a wide variety of neurobehavioral analyses. My goal is that each student in my lab will have the opportunity to publish their research and/or present it professionally.
