Duke University (2002–2006): B.S. in Biology and B.A. in Religion
UC Santa Barbara (2008–2015): Ph.D. in Earth Science
I received my Ph.D. here at UCSB, gaining research experience both on and off campus. I’ve helped explore new fossil localities in Madagascar and in the Andes of Chile, and also worked extensively at the American Museum of Natural History (NYC), examining important collections and learning the basics of fossil preparation. In 2011 I received a Fulbright Fellowship to study extensive fossils collections in Argentina—work that proved foundational for my dissertation (and ongoing research).
As a graduate student I also developed a strong passion for teaching. I was a teaching assistant for nine courses and eventually became a graduate student Teaching Associate (instructor of record) for two courses. For high school students, I've planned and taught a five-week short-course in paleontology, and also participated in research mentorship. In an effort to hone my craft as an educator, I’ve been highly involved with the Summer Teaching Institute for Associates—first as a participant, then a graduate student facilitator, and more recently as a guest speaker/panelist. In conjunction with my Ph.D., I also received UCSB's Certificate for College and University Teaching.
After finishing my dissertation, I've remained at UCSB as a lecturer, teaching classes focused on paleontology, evolution, and geology. I also serve as the Earth Science Department's educational outreach coordinator. Having received a B.A. in religious studies, I’ve maintained an active interest in the dialogue between science and religion, especially in critically addressing the conflict between evolution and creationism/intelligent design. Towards that end, I have designed courses and participated in a wide array of seminars that explore these ideas in an open and engaging manner.
My research focuses on describing several newly discovered species of mammals that lived ~15–20 million years ago in the Andes of Chile. The fossil mammals of South America include many peculiar forms that diversified while the continent was a large island. The land bridge between North and South America formed “only” 3 million years ago, which resulted in a dramatic faunal turnover and the extinction of many interesting groups, some of which paleontologists occasionally dig up and identify.
The fossils I study from the Chilean Andes are unique in that (1) they were preserved in actively volcanic regions, which have helped provide a robust stratigraphic and geochronologic framework for research; (2) they range in age from about 15–20illion years old, thus representing a continuous fossil sequence with evolutionary and biogeographic implications; and 3) these fossils include many new species known only to this region. This unexpectedly high degree of endemism in the Andes helps us better understand the ancient diversity of South American mammals (until recently, our knowledge of mammalian evolution in South America has been biased by large collections from Patagonian lowlands). I investigate the taxonomy, biogeography, and evolutionary relationships of some of these groups of ancient mammals.
