About Us

Our research explores the neurobiological basis of addiction (tobacco, alcohol, marijuana) and mood/anxiety disorders (depression, bipolar disorder, and PTSD). We use state-of-the- art brain imaging technologies Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) to investigate certain receptors in the brain and neural mechanisms that are thought to underlie these disorders.

Taking part in our research will improve our understanding of addiction and mood disorders so that they can be treated more effectively in the future.

Participate in Our Research

We are continuously recruiting volunteers to participate in our imaging studies. Each study has different requirements. We are looking for people with depression, bipolar disorder and PTSD. We are also recruiting individuals who smoke tobacco, use alcohol or marijuana, or use e-cigarettes/vape. We also recruit individuals who are healthy to act as a comparison group.
