My research involves the use of sedimentary and geochemical approaches to solve paleobiological problems.  I have just been awarded a grant from the National Science Foundation to study the link between extreme volcanism, global warming and ocean acidification following the End Permian mass extinction, the largest biotic crisis in Earth history.

I am also currently involved with a combined sulfur and oxygen isotope study of the Late Paleozoic icehouse to greenhouse climate transition. By using stable isotopes of sulfur preserved in brachiopods and oxygen isotopes preserved in conodonts, I hope to better understand sulfur cycle dynamics during this important warming event.
