My research focuses on understanding the systematic biology of flowering plants. This field of inquiry includes the study of taxonomy (i.e., species discovery and description), the study of phylogeny (i.e., evolutionary relationships among species), and the study of evolutionary processes (e.g., speciation, historical biogeography). Much of my research centers on the systematics of the frankincense and myrrh family, Burseraceae. However, members of my lab have pursued systematics projects involving a range of plant taxa across the globe, from Himalayan sunflowers to the Virginian saltmarsh mallow.

I am pictured above holding a herbarium sheet of Chrysogonum virginianum (Asteraceae), a native wildflower known as "Green-and-Gold." This name also describes Mason's university colors! Photo credit: Evan Cantwell, GMU.

In addition to my research and teaching responsibiIities, I am director of the Ted R. Bradley Herbarium at GMU and am engaged in making this valuable resource of information about the Virginia flora more accessible via the internet.
