About me

I grew up in Charlotte, NC before going to school at the University of North Carolina at Chapel Hill. There, I double majored in biology and art, often finding a synergy between my science classes and studio work. I worked on a few research projects in ecology labs in undergrad, namely helping to develop a citizen science project that monitors arthropod phenology relevant to migrating bird species. Before starting at Davis, I worked for a year and a half as a lab manager and research assistant for the Echinacea Project, based at the Chicago Botanic Garden. I am excited to be joining the Population Biology Graduate Group and take advantage of California’s diverse ecosystems to carry out my studies. When not doing research, I am making art with all kinds of materials (clay, weaving, drawing, collecting), doing yoga, and spending time outdoors.


I am interested in how spatial and temporal structure influences species interactions. Particularly, I want to understand how a plant species’ clustering in space and flowering/leafing out schedule affects its interactions with pollinators and herbivores. Can the spatial and temporal structure of a plant species’ floral resources be used as a predictor for that plant species’ diversity of linkages with short-distance or long-distance foraging pollinators? How does the clustering and timing of leaf production affect the community of herbivores that assemble on a plant species? I am also interested in testing an idea of “spatial structure niches,” where plant species with similar spatial structure-time curves replace each other over a season.
