Detailed Biography:

H. Ronald Kaback has been a member of the faculty at UCLA since he joined the Depts. of Physiology and Microbiology, Immunology & Molecular Genetics, as well as the Molecular Biology Institute, in 1989 as a full professor. Dr. Kaback earned his B.S. at Haverford College and his M.D. at The Albert Einstein College of Medicine, where he also did an internship in Pediatrics. After a year as a graduate student, he became a Commissioned Officer in the USPHS at the NIH and subsequently became at Staff Associate. He then moved to the Roche Institute of Molecular Biology in Nutley, NJ where he later became Head of Biochemistry before coming to UCLA. He is a member of the National Academy of Science and is the recipient of many awards for his work.
