Research Interests

I am interested broadly in the evolution of host-symbiont interactions across spatial and temporal scales. My research largely encompasses studies on: 1) systematics and phylogeography of symbionts and their hosts; 2) molecular evolution of host-symbiont co-evolutionary interactions; and 3) symbiont community and trait diversity, with an emphasis on host specificity. I use birds and their parasitic and mutualistic microbes as a model system with which to study these processes. My current research is focused on higher-level systematics, species delimitation, and host specificity of avian malaria parasites, as well as avian gut microbiome diversity, distribution, and function. I have previously published on avian phylogeography, hemoglobin evolution, and natural history, and I maintain research interests in these areas. My research is heavily dependent on scientific collections, and I strive to actively contribute to these resources.
