Barbara A. Horwitz

75th APS President (2002-2003)
Barbara A. Horwitz
(b. 1940)

Barbara A. Horwitz is a professor of physiology in the section of Neurobiology, Physiology and Behavior, and Vice-Provost of Academic Personnel at the University of California, Davis. Dr. Horwitz received her doctorate in physiology from Emory University in Atlanta, Georgia, in 1966 and did her postdoctoral training at both the University of California Los Angeles and Davis locations. She became an assistant professor at UC Davis in 1972, an associate professor in 1975, and was appointed a full professor of physiology in 1978. Dr. Horwitz also served as the chair of the Department of Animal Physiology at UC Davis from 1991-93 and chair of the Section of Neurobiology, Physiology & Behavior at UC Davis from 1993-98.

Dr. Horwitz's research centers on the genetic, neural, and hormonal regulation of energy balance. Her current studies are focused on the underlying mechanisms associated with altered regulation of energy balance in genetic and diet-induced animal models of obesity; the cellular and molecular mechanisms underlying sympathetic stimulation of energy expenditure in brown adipocytes; the role of novel uncoupling proteins in energy balance and oxidative stress; and the physiological basis of altered metabolism and thermoregulation during aging. In addition to her research, Dr. Horwitz directs an NIH-funded Initiative for Minority Student Development which is designed to increase the number of underrepresented minorities in biomedical research careers.

Dr. Horwitz has authored/co-authored over 180 research papers, many of which have been published in the American Journal of Physiology and the Journal of Applied Physiology. She has served on the editorial board of the Journal of Applied Physiology (1975-78); as a section editor for the Handbook of Physiology  Adaptation to the Environment (1991-92); and as an associate editor for News in Physiological Sciences (NIPS) (1994-96). She has been a grant proposal reviewer for the National Science Foundation [panel member for Regulatory Biology (1981-83); for the instrumentation program (1993); and for predoctoral fellowships (1994-96)]. She was a member of the NIH Respiratory and Applied Physiology Study Section (1995-99), and an hoc reviewer of grants for the Veterans Administration, the California Sea Grant College Program, Texas Tech University, the USDA, and the American Heart Association, as well as for numerous scientific journals including the American Journal of Physiology, Journal of Applied Physiology, Science, Journal of Physiology & Pharmacology, American Journal of Clinical Nutrition, European Journal of Pharmacology; Hormone and Metabolic Research, Journal of Nutrition, Journal of Comparative Physiology, Journal of Thermal Biology, Journal of Biological Chemistry, Endocrinology, Obesity Research, Physiology and Behavior, and Proceedings of Experimental Biology and Medicine. Dr. Horwitz has served on the Executive Committee (1989-92) and as chair of the Finance Committee (1993-96) of the North American Association for the Study of Obesity. She has also served on the council for the Society for Experimental Biology and Medicine (1990-94) and is currently president of that Society.

Dr. Horwitz became a member of the APS in 1969. In addition to her editorial service for NIPS and the Journal of Applied Physiology, Dr. Horwitz has been active on a variety of APS committees, including the Public Affairs Committee (1977-79), the Women in Physiology Committee (1986-89), the Steering Committee for the Exercise and Environmental Physiology Section (1987-90), the Education Committee (1983-85, 1990-93), the APS Council (1993-96), the Committee on Committees (1994-96), and the Long Range Planning Committee (1997-2000). She has participated in the Frontiers of Physiology and Explorations in Biomedicine programs, hosting K-12 and community college science teachers (1995, 1998, 1999), and she is currently serving in the mentoring program (1993-present).

Dr. Horwitz has been the recipient of several awards. These include the APS Arthur C. Guyton Physiology Teacher of the Year; the University of California Presidential Award for Excellence in Fostering Undergraduate Research; the UC Davis Prize for Teaching & Scholarly Achievement; the Distinguished Teaching Award from UC Davis; and an NIH MERIT Award. She is a Fellow of the American Association for Advancement of Science, vice president/member of the National Executive Council of the Phi Sigma Biological Sciences Honor Society, and a member of the North American Association for Study of Obesity, the New York Academy of Sciences, and the Society for Experimental Biology and Medicine.
