I’m broadly interested in community ecology. In particular, I’m interested in understanding distributional patterns of biological diversity and how different factors (both natural and anthropogenic) can affect these patterns. My research utilizes population genetic techniques to characterize within-species genetic variation and to test predictions based on ecological theory. Previous work has outlined patterns of range expansion and island biogeography in Neotropical mangrove species.


In 2017, I began my PhD in the Preziosi and Rowntree labs. My project will examine the relationship between within-species genetic diversity and ecosystem function. Specifically, I will address questions about the effect of genetic variation within Neotropical mangroves on associated community structure, leaf decomposition, and seedling performance.


Apart from research, I’m currently enjoying the process of learning to be a father and meandering walks to the park.
