SUMMARY
My research focuses on understanding mechanisms influencing food selection and intake in herbivores, in order to create more efficient alternatives for managing the production, health, and welfare of animals and the integrity and sustainability of the landscapes they inhabit. I am interested in principles that underlie foraging behavior with the aim of obtaining reliable
knowledge on the plant species, parts, and chemicals an herbivore selects while grazing, as well as why, how, and when specific foods are ingested. More recently, my research has focused on exploring the ability of herbivores to self-select natural plant products to recuperate from illness, and on taking innovative behavioral and landscape interventions aimed at enhancing the
functioning of agroecosystems.
