The End-Triassic Mass Extinction

The primary focus of my research at Brown University was the end-Triassic Mass Extinction. This ecologic and climatologic disaster, which occurred ~200 million years ago, was one of the most destructive in the history of life. It led, many would argue, to the development of the modern ecosystem and paved the way for the dominance of dinosaurs. My goal was to see what changes where happening in the ocean at that time (Read more).

My research there focused on the Plio-Pleistocene boundary, which, in Florida, was a significant regional extinction event in the marine realm. I collaborated with Bill Weinlein under the supervision of Peter Harries.  Our goal was to test the hypothesis that changes in ocean circulation resulted in changes in the amount of nutrients delivered to coastal ecosystems by altering seasonal upwelling.
