I have two research fields: nutritional ecology with an emphasis on vertebrate herbivores and the biology of sea turtles. My nutritional ecology research focuses on how and to what extent nutrition acts as a controlling mechanism on an organism’s growth and reproductive output. I am also interested in the interrelationships of diet selection, digestive processing, gut fermentations, and gut morphology. My sea turtle research interests are very broad, but studies are integrated into two themes: the past and present roles of sea turtles in marine ecosystems and connectivity of sea turtle populations in the Atlantic. I am particularly interested in studies of foraging ecology, growth, and demography.
