I am a paleontologist at the Field Museum in Chicago, and National Geographic Explorer. My work focuses on mass extinctions and the early evolution of important groups like dinosaurs, crocodiles, and mammals. Most of my research takes place in Zambia, but I also work in Antarctica and around the USA in Arizona and Montana.
I am a born-and-raised Michigander and have been fascinated with the natural world all my life. As a child I loved the outdoors, and my dinosaurs, and it was when I was in middle school when I first began to understand the explanatory power of evolution. "You mean evolution connects the dinosaurs in my books with the woods in my yard?!" I've never looked back.
