Tom Brenna, PhD, is Professor of Pediatrics, of Human Nutrition, and of Chemistry at the University of Texas at Austin since 2017, after 27 years as a Professor of Human Nutrition, and of Food Science at Cornell University in Ithaca, NY. His group’s basic research into the chemical, biochemical, metabolic, genetic and ecological aspects of fatty acids have had a decisive influence on modern knowledge of these key nutrients. In the 1990s his research group was among those contributing to the recognition that dietary omega-3 fatty acids are required for proper brain and retinal function in developing infants. His group’s work has transformed our understanding of the LCPUFA biochemical pathways, and has defined genetic variation central to fatty acid requirements. He is the fourth scientist to be honored with both ASN’s Osborne and Mendel Award for outstanding contributions to basic research in nutrition and the ASN’s Robert Herman Award for advancement of clinical nutrition (2013).
