About me

I grew up in Charlotte, NC before going to school at UNC Chapel Hill. There, I double majored in biology and art. I started becoming interested in ecology while studying arthropod phenology relevant to migrating birds in North Carolina. Before coming to Davis, I was lucky enough to work in the tallgrass prairies of Minnesota and a geothermal stream system in Iceland. When not doing research, I like to make all kinds of things and explore the synergy between artmaking and science.


I am interested in organisms that rely on resource patches that are rare in space and time. These ephemeral resource patches often act as ecological epicenters, or what Charles Elton referred to as “centers of action,” where species interactions, niche partitioning, and behavioral/morphological adaptations are intensified. Particularly, I am using carrion beetles to study the effects of ephemeral resource patches on reproductive output and population characteristics.
