Research Description

My research interests are at the intersection of paleontology with stratigraphy and geochemistry using conodont microfossils. Only the small tooth-like elements, composed of calcium phosphate, of conodont animals are usually preserved, which makes understanding the paleobiology of these extinct eel-like creatures challenging. My students and I use conodonts to determine the age of the rocks that contain them, and we study the oxygen and carbon isotopes in the conodonts and the rocks to interpret paleoclimate.
