Our lab tries to solve questions of arthropod phylogeny and biogeography. We use data from DNA sequencing, Scanning Electron Micrography (SEM), light imaging, and GPS. We analyze these data with computer phylogenetics software, and other computer analysis tools.
Students who are interested in working with us need to be aware that our lab cannot manage short-term projects in which the student only has a semester to complete, and a few hours a week to work in the lab. A research project in our lab usually starts with a trip to collect specimens, which in itself can take many months to fund and arrange. After we collect specimens, it can take months to familiarize oneself with the relevant literature, and then some more months to learn the taxonomy of a particular group. Only then can students start isolating DNA and learn about phylogenetic analyses. Because there are so many steps, we only accept students who can commit to more than one semester, can travel, can commit many hours per week, and are self-directed.
