My career goal is to domesticate perennial plant species that provide novel raw materials, revenue for farmers, and maintain ecosystem services and water and energy cycles in environments with limited water. Perenniality incorporates a new level of analysis into the evolving theory of domestication, which I am deeply interested in. I have done germplasm collection and evaluation, research on ecophysiology (main focus of my work), product extraction and characterization, and some breeding on perennial species: Lesquerella, Silphium, Lupinus (Seed-oil), Hesperaloe, Yucca, Kenaf, Bromelia (Fibers), Guar, Prosopis, and Cercidium (Gums), Guayule, Grindelia (Resin and Rubber), among others, financed by public institutions and industry. I am head of Departamento de Plantas Actuales (MEF, CONICET). We work in collaboration with Universidad de Buenos Aires, INTA, University of Arizona, CSIC (Spain), and the Land Institute (USA). I teach Plant Physiology and Crop Ecophysiology (Universidad de la Patagonia, Argentina) and have taught at the University of Arizona, Universidad de Buenos Aires, and other institutions. Studies: Agronomy (University of Buenos Aires, Argentina) M.Sc. Agronomy and Plant Genetics (University of Arizona, USA) Ph. D. Arid Lands Resource Sciences (University of Arizona, USA) Current positions: Investigador Principal (CONICET, Argentina) Professor (Plant Physiology, UNPSJB, Argentina).
