Peter joined our department in July of 1976 and has been an integral member of PBIO and the UW School of Medicine. Peter received his B.S. in Biology from St. Lawrence University and his PhD in Pharmacology from Georgetown University. He completed postdoctoral training in the Laboratory of Neurophysiology at the NIH and at the Physiological Laboratory in Cambridge with Sir Alan Hodgkin. Peter’s research has addressed fundamental questions about the cellular physiology of retinal neurons. With Winfried Denk, Peter introduced the use of 2-photon Ca2+ imaging in retina research and used it to provide the first description of direction selective Ca2+ signals in starburst amacrine cells. Peter has made significant contributions to our current understanding of vertebrate phototransduction. Over his career, he taught not only for the department, but also in the medical school. Peter served (twice) as the course director for Cell Physiology in the medical school. The second time, he took over for Wayne Crill when he retired. The course was very popular and often received the Best First Year Course award. Peter was awarded the University of Washington Distinguished Teacher Award twice (in 1981 and1983) and the School of Medicine’s Outstanding Teaching Award three times (in 1983,1986, & 1988). He served on the Editorial Board for the Journal of Physiology from 1993 to 2000. Peter also served as the Director of our PBIO Graduate Program from 2010-2022. We are also grateful for the contribution of Peter’s artistic efforts for many of our departmental retreat t-shirts.
