Our goal is to understand how the brain controls motivated behaviors, and how maladaptive
changes in brain circuits relate to neuropsychiatric diseases such as addiction and depression

We Welcome Anne van den Heuvel for her Research Internship!

Warm Welcome to Our New Undergraduate Researchers: We’re excited to welcome Michael Tanios and Ava Fu to our research team! Welcome aboard, Michael and Ava!

We are thrilled to announce that Petra Mocellin has joined our team as a postdoctoral researcher! Welcome, Petra!

Our new research article is online. We describe two dopamine cell subtypes with sustained or transient activity patterns in both cell bodies and axon terminals and propose that these subtypes represent the parallel encoding of a behavioral state and its temporal dynamics — Congrats to Han!
