David Raubenheimer

David Raubenheimer is a Professor at The University of Sydney's BIO department. His research spans animal physiological ecology, population ecology, invertebrate biology, animal diet and nutrition, ecological physiology, vertebrate biology, community ecology, marine and estuarine ecology, zoology, and animal physiology - systems. He joined the University in April 2013 as Leonard P Ullmann Chair in Nutritional Ecology. His work focuses on how nutrition-related aspects of an animal's environment interact with its biology to determine health and fitness outcomes. His studies of insects, fish, birds, and mammals have contributed to understanding dietary causes of obesity and other nutrition-related issues. The interdisciplinary environment of the Charles Perkins Centre supports his research into solutions for global challenges.

David Raubenheimer is a researcher in Nutritional Ecology, focusing on the interplay between nutrient intake, health, and ecological behavior. His work explores how macronutrient ratios influence cardiometabolic health, aging, and longevity, as well as the role of nutrient balancing in animal adaptation and human obesity. Raubenheimer's research integrates nutritional geometry, foraging behavior, and ecological modeling to understand how organisms optimize nutrient intake under varying environmental conditions. His studies also examine sex-specific effects of nutrition on reproduction and lifespan, as well as the ecological implications of dietary choices in invertebrates and vertebrates.
