Macroevolution - Paleontology - Functional morphology - Mammalogy

Research Interests

I'm an evolutionary biologist interested in how functional traits influence macroevolution. My preferred study organisms are mammals, both modern and extinct. Much of my research has focused on early mammals from the Mesozoic Era (or Age of Dinosaurs), but I've also studied modern mammals to address questions about evolutionary processes, convergence, and functional morphology. 

I'm especially interested in the tempo of ecological diversification during major mammalian radiations, and my research has examined both very broad radiations (e.g., all mammals and other synapsid groups) and mammalian subgroups (e.g., phyllostomids, an incredibly diverse group of bats). I'm performing this research as an assistant professor of biology at Oregon Institute of Technology. Formerly, I was a postdoctoral researcher at the University of Washington, working in Sharlene Santana's lab and Greg Wilson Mantilla's lab. I obtained my PhD (2018) through the Committee on Evolutionary Biology at The University of Chicago, studying in the labs of Zhe-Xi Luo and Kenneth Angielczyk. I'm a former fellow at the Field Museum of Natural History in Chicago.

Teaching & Outreach

Pedagogy is a central focus of my career in academia. I am currently teaching Human Anatomy & Physiology courses at Oregon Tech. Prior to entering graduate school, I taught biology for four years at Wawasee High School in Indiana. And recently I taught a paleontology field methods course through the University of Washington. 

I have been an active participant in several museum outreach programs, including Dozin' with the Dinos at the Field Museum of Natural History. This program gives children an opportunity to interact with scientists and spend the night at the museum. 

During the summers, I assist scientists from the University of Washington (Wilson Mantilla lab) with paleontological fieldwork in Montana. This includes helping with the DIG Field School (below), which is a professional development program for K-12 teachers.

Our campsite was especially busy because 30 teachers from had joined us for the DIG Field School. The lake is the Fort Peck Reservoir.
