Felix Bronner, Ph.D., is professor emeritus of biostructure and function and of nutritional science at the University of Connecticut Health Center. A doctoral thesis on calcium metabolism in adolescent boys, under the supervision of Professor R.S. Harris at MIT, was the beginning of a long research career in bone and calcium metabolism and nutrition. A major aspect of Dr. Bronner's research has been the quantitative elucidation of active and passive calcium absorption in human and experimental animals, a definition of renal calcium movement, and quantitative analysis of plasma calcium homeostasis., Author of more than 100 research papers, 77 book chapters, and editor of 54 books and treatises, including serving as founding editor of Current Topics in Membranes and Transport, Dr. Bronner has organized many scientific meetings and symposia, has trained graduate students and many postdoctoral fellows, and is the recipient of the 1975 Andre Lichtwitz Prize awarded by the French National Institute for Health and Medical Research (INSERM) for excellence in calcium and phosphate research. In 1996 he was awarded an honorary doctorate by the École Pratique des Hautes Études under the auspices of the French Ministry of Higher Education. He has been a visiting professor at the Universities of Cape Town, Tel Aviv, and Lyon, and at the Pasteur and Weizmann Institutes.
