I am interested in the origin, evolution, and adaptation of species and maintenance of symbioses, and in particular, how different factors may influence patterns of diversification. More specifically I am interested in how we can use diverse tools including molecular methods, next-generation sequencing, and comparative genomics with field-based research to address these questions. My research interests range from population and species level questions concerning biogeography and the effect of geologic and climatic oscillation events to higher-level phylogenetic questions regarding diversification of lineages to the role that host-associated microbes play in the ecology and evolution of insects. My research program is organismal-based and aims to integrate data from diverse disciplines such as genetics, genomics, entomology, ecology, and geography to address questions of how biological and physical processes interact to drive evolution. Although my work relies in large part on inferring molecular phylogenetic trees in a model-based statistical framework, my interest includes how we can use those trees to inform larger-scale evolutionary patterns. These questions include why species are found where they are, how long they have been there, what factors may have promoted their diversification, how species interactions shape the evolutionary history of both players, and how this may inform us about broader evolutionary questions outside of the focal taxonomic group alone including modern issues like invasive species, climate change, and conservation. By uncovering the diversity and putative function of host-associated microbes we may begin to understand how these interactions are driving the evolution of both partners. Much of my research focuses on gut-associated bacteria in the ants. By coupling this information with data on diet, trophic ecology, evolutionary history and biogeography, I hope to gain a better understanding of how intimate interactions influence patterns of diversity.
