Education / Training

  • 1959, B.A. in Zoology, Cornell University, Ithaca, New York
  • 1964, Ph.D. in Physiology, Harvard University, Cambridge, Massachusetts
  • 1964-67, PHS Postdoctoral Fellowship, Cornell University Medical College, New York


I retired July 2009, after 42 years as a faculty member in the Physiology department, and moved to Oregon. My address is 3302 Stoney Ridge Road, Eugene, OR 97405. My research was on kidney function in health and disease. I used mainly kidney clearance and micropuncture techniques on small laboratory animals, and, in my last few years, two-photon microscopy. I believe that a combination of micropuncture techniques with the new sophisticated in vivo imaging methods shows great promise for future research. My research dealt with topics such as tubular reabsorption and secretion of organic compounds, acute kidney injury, ureteral and single nephron obstruction, tubuloglomerular feedback, glomerular permeability, and polycystic kidney disease (PKD). I found that ingestion of alkalinizing citrate salts (e.g., potassium citrate) in rats with PKD resulted in dramatic slowing of the disease; whether this treatment would be beneficial in people with PKD should be studied. My wife, Judith A. Tanner, Ph.D., helped me with my research throughout my career.
