My research investigates the structure and dynamics of ancient ecosystems--particularly those of the Mesozoic Era (about 65 to 250 million years ago).
I am interested in how ancient communities of organisms differed from modern
ecosystems in composition and organization. Much of my work focuses on tapping
information available in permineralized coprolites (fossil feces), but I also examine
other trace and body fossils. My work focuses on understanding interactions among
ancient organisms, and deducing the environmental conditions in which these organisms
lived and were fossilized. I use a multidisciplinary approach by examining
geological, biological, and chemical characteristics of fossils and compare the fossil
evidence with modern ecosystems to derive paleoecological interpretations.
