David L. Farrens, Ph.D.

  • Associate Professor of Chemical Physiology and Biochemistry, School of Medicine
  • Neuroscience Graduate Program, School of Medicine
  • Graduate Program in Biomedical Sciences, School of Medicine

Biography

Dr. Farrens obtained his undergraduate (1985) and Ph.D. (1991) in chemistry from the University of Nebraska-Lincoln.  His graduate work involved physical and biochemical studies of the plant photoreceptor phytochrome (carried out under the supervision of Dr P.-S. Song), followed by similar work at RIKEN in Tokyo with Dr. Furuya.   He then moved to MIT to work on the visual photoreceptor rhodopsin with Dr H. G. Khorana (1992–1995), and then at UCLA with DrW. L. Hubbell (1996).
  
In his laboratory at OHSU, Dr. Farrens (and colleagues) develop and use novel biochemical and physical methods to identify common structural mechanisms involved in the activation and attenuation of G-protein coupled receptors (GPCRs).  Their work focuses primarily on rhodopsin and the cannabinoid receptor CB1, studying how these proteins interact with their affiliate signaling partners (G-proteins, arrestins and kinases).
