Robert Alpern, MD
- Ensign Professor of Medicine (Nephrology)
- Dean, Yale School of Medicine
Dr. Robert J. Alpern attended undergraduate school at Northwestern University, where he majored in Chemistry. He received his M.D. degree from the University of Chicago Pritzker School of Medicine in 1976, and received residency training in Internal Medicine at Columbia Presbyterian Hospital in New York. Following this, he performed a postdoctoral fellowship in Nephrology in the Cardiovascular Research Institute at the University of California, San Francisco. In 1982, Dr. Alpern joined the faculty at the University of California, San Francisco, and in 1987 he was recruited to the University of Texas Southwestern Medical Center as Chief of the Division of Nephrology. At Southwestern Dr. Alpern held the Ruth W. and Milton P. Levy, Sr. Chair in Molecular Nephrology and the Atticus James Gill, M.D. Chair in Medical Science. In July 1998 Dr. Alpern was appointed Dean of Southwestern Medical School and in June 2004, he moved to the Yale University School of Medicine to become the Ensign Professor of Medicine and Dean of the medical school. Dr. Alpern’s research has focused on the regulation of kidney transport proteins. In addition Dr. Alpern has been highly committed to teaching and clinical medicine. In 2000 he was elected President of the American Society of Nephrology. He was elected to the American Society of Clinical Investigation, the Association of American Physicians and the Institute of Medicine and has served on the Advisory Council of the National Institute of Diabetes and Digestive and Kidney Diseases.
Research on the regulation of kidney transport proteins has helped to define the mechanisms by which the kidney transports acid. Subsequently has focused on the mechanisms by which kidney cells sense excess acid and initiate a signaling cascade that alters the expression, cellular location, and function of many proteins in the cell, resulting in enhanced acid transport and urinary excretion.
