aquatic ecology, evolution, and conservation

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.

My past research has focused on the evolutionary origins of trait diversity and their consequences for ecosystem function – from a deep-time community phylogenetics perspective in coastal marine invertebrates, to a rapid-evolution perspective in freshwater foodwebs, making use of experimental evolution and genomics tools in the threespine stickleback system.


Before wading into aquatic ecology, I worked on ecological and evolutionary mechanisms behind simultaneous plant and grazer invasions in the Gulf Islands of British Columbia.
