Research Assistant Professor, University of Utah. Researcher for Instituto de Conservación de Ballenas, Argentina.
Dr. Valenzuela uses stable isotopes to study diet, foraging ecology and migration of a wide array of animals. He received a Licenciatura degree in biology from the Universidad de Buenos Aires and a Ph.D. from the University of Utah. Dr. Valenzuela’s work with southern right whales off Península Valdés focuses on the use of stable isotopes from skin samples and baleen plates to study foraging strategies, migratory patterns and habitat use.
Currently, his research centers on understanding the spatial distribution of stable isotopes across landscapes and their use as location markers in studies of the movement of animals and humans as well as the geographic origins of food. His current work also utilizes stable isotopes to study human and animal nutrition.
Dr. Valenzuela is the co-creator and manager of isesecol-ar (an electronic forum) and a blog/website aimed at enhancing communication among researchers interested in the use of isotopes in ecology and the development of this field in Latin America.
