The motivation of my research is to better understand the impacts of climate change on marine life. Specifically, I work on the fossil record of Radiolaria, because this particular marine plankton group has played a critical role in ocean food webs and geochemical cycles for hundreds of millions of years; they also happen to be well-preserved and abundant in deep sea sediments. In 2013, I received my undergraduate degree in Literature from UC Santa Cruz. After working as a park ranger, exploring the public lands of Oregon and California, I decided to shift academic focus from literary studies to paleontology upon entering graduate school. For my MS, I worked with Alycia Stigall at Ohio University to constrain the timing of a major evolutionary radiation among marine invertebrates (The Great Ordovician Biodiversification Event) using brachiopod fossils from North America. Now at UNR with Paula Noble, I work on characterizing marine zooplankton evolutionary patterns in the context of paleoclimate records. My PhD work involves the collection, analysis, and geographic comparison of radiolarian fossil datasets from the Neogene and Quaternary.
