• Associate Professor

Research Interests

I am a clinical neuroscientist focused on using neurobiological measures to improve treatment for alcohol and addictive disorders. My training and expertise span behavioral genetics, functional neuroimaging, experimental pharmacology, and “human laboratory” paradigms. I am also a licensed clinical psychologist in the state of Colorado. My current work, funded by grants from the National Institute on Alcohol Abuse and Alcoholism (NIAAA), focuses on evaluating novel medications for Alcohol Use Disorder (AUD).
