I am a postdoctoral research scientist in the Integrative Research Center at the Field Museum of Natural History in Chicago.
My research uses fossil and extant data from multiple temporal and spatial scales to study how ancient vertebrate communities were structured, how they responded to environmental perturbations, and how this influenced the macroevolution and biodiversity of clades in these systems.
I'm particularly interested in the dinosaur-dominated ecosystems of the Late Cretaceous of North America, as this was a period of high biodiversity, frequent environmental changes, and was truncated by a major mass extinction. To answer my research questions I use a combination of tools, including quantitative biodiversity ordinations, stable isotope analyses, osteohistology, and morphometrics.
In addition to my research, I am heavily involved in educational & public outreach programs, as well as museum exhibit development. I also pursue photography as a hobby & use it to document the many interesting places my work takes me.
