Zachary Freyberg is an Associate Professor at the Department of Psychiatry, University of Pittsburgh. Zachary does research in Neuroscience, Endocrinology and Cell Biology. The central theme of the Freyberg lab is elucidating mechanisms of dopamine signaling, particularly at the presynaptic level. To investigate this, the lab is developing approaches in live multiphoton imaging within the Drosophila model, examining signaling using the pancreatic beta cell model and cryo-electron tomography.
