I am an aquatic community and evolutionary ecologist interested in the processes that determine the number and type of species we find coexisting in a particular community, and control the way those communities function. At Northern Arizona University, I am working on the effects of changing temperature and precipitation on aquatic connectivity, species distributions, and genetic diversity across arid landscapes.

Masters Student
Environmental Science and Policy

In collaboration with the Cottonwood Ecology Group, I am studying the impacts of leaf plasticity on aquatic community composition in cottonwood leaf litter from three common gardens in Arizona and Utah. I am interested in investigating the effects of geographic variation on arthropod colonizers and decomposition. Since graduating from Central Michigan University with a B.S. in Natural resources Biology, I have spent time traveling and working internationally.

I am an environmental science student in biology interested in studying and utilizing modern techniques to monitor, maintain and improve natural resource management. I am particularly focused on the conservation of water, soil and ecological resources and how they tie in with agriculture which is the largest land use on the planet.
