Peter S. Aronson

C.N.H. Long Professor of Internal Medicine and Professor of Cellular and Molecular Physiology. Made fundamental contributions to understanding transport processes in gut and kidney that regulate urinary excretion of sodium, hydrogen ions, chloride and oxalate. Defined molecular properties and regulation of membrane proteins mediating sodium-hydrogen ion exchange and organic anion-chloride exchange. Identified mechanisms by which calcium oxalate crystals cause inflammation and tissue injury.
