Paul E. M. Phillips, Ph.D.
Professor
Department of Psychiatry & Behavioral Sciences Last updated: Paul graduated in Physiology from the University of Liverpool in 1993. He completed his Ph.D. in Neuroscience in 1999 from St Bartholomew's and the Royal London School of Medicine and Dentistry (University of London) under the supervision of Jon Stamford. His postdoctoral work was with with Mark Wightman at the University of North Carolina at Chapel Hill and was appointed as a Research Assistant Professor in Psychology at UNC in 2003. He joined the faculty at the University of Washington in 2004. The key focus of our lab is to more precisely define this role of dopamine neurotransmission in cognition and behavior, and to use this information to address how molecular processes that control this transmitter may alter behavior and lead to psychiatric disease. Our investigations use traditional behavioral paradigms such as operant behavior and classical conditioning as well neuroeconomic approaches to study decision making. One of the main tools of the lab is fast-scan cyclic voltammetry. This is a rapid electrochemical technique that can detect dopamine several times a second and chemically resolve it from other electroactive species. This technique has been particularly useful for elucidating the precise temporal relationship between released dopamine and behavior, as well as probing the dynamics of the system. We combine these recordings with behavioral procedures (food and drug self-administration, decision making and classical conditioning), neuropharmacology (systemic administration and site-specific intracranial microinjections), viral-mediated gene delivery, intracranial stimulation and computational modeling.
