I am an assistant professor of geochemistry at Western Carolina University, focused on understanding environmental changes in the oceans over geologic time. I’m especially interested in the Permian and Triassic periods – the warm transition interval between the Paleozoic and Mesozoic eras – and on the two major mass extinctions that paved the way for our modern marine ecosystem. To study the deep past, I apply a set of geochemical tools to marine sedimentary rocks from around the world. As a field geologist, I’ve had the opportunity to work on four continents, and across much of the geologic time scale. I’ve also introduced dozens of students to the practice of field geology through my summer field courses in southwestern Montana.

Panel 1

What’s new?

Cretaceous polar environments were unlike anything that exists in the modern world – while the poles were much warmer than today, they still experienced months of darkness every year.

How do marine environments respond to such conditions? We went to Antarctica to find out. Our paper on Seymour Island is now in print (PDF).
