Decoding the biology of addiction

We identify the neurobiological mechanisms underlying drug addiction and develop novel pharmacological and non-pharmacological treatments to help people with substance use disorders.

The Approach

From genes to behavior

“From a single gene to the whole person, addiction touches every level of biology, so we study every level.”
