Caroline Strömberg is interested in how plants and animals interact through ecology and evolution. She uses phytoliths (plant-opal), which form in the tissue of plants such as grasses, to document the origin and spread of grass-dominated habitats in North America during the Tertiary, and to examine how this ecological change related to the evolution of mammals, in particular ungulates. She has also used phytoliths preserved in fossilized dinosaur dung to elucidate the early evolution of grasses and grazers. Caroline received her Ph.D. from the University of California at Berkeley. Her post doc project at the NRM concerns the evolution of grasslands in Eurasia during the Miocene.
