About me

I grew up in Missoula, MT, where I became interested in the field of ecology in high school. I helped develop a research project on Steller’s jay alarm calling and predator avoidance that sparked my passion for ecology as a way to understand the natural world. As an undergraduate, I attended Stanford University, where I majored in ecology and evolutionary biology. At Stanford, I researched resource partitioning in a native California ant community, drought and pollinator network structure in the Colorado Rockies, and bird biodiversity and ecotourism in Costa Rica. After graduating I spent a year as a lab technician at Princeton University working on a project connecting rapid evolution to coexistence in two fruit fly species. Outside of my research interests, I enjoy hiking, cooking and baking, and playing racquetball.

Research

I am broadly interested in how climate change is altering interactions between different species, as a result of phenological shifts, temperature extremes, or changes in precipitation. Currently, I’m researching how interacting temperature and precipitation cues may impact the timing match/mismatch between western monarch migration and milkweed availability, using a series of field sites in the Central Valley and California Coast Range. I’m also working on an ongoing project using citizen science photos to examine the phenology of different native California milkweed species across their ranges.
