This site is designed to disseminate the results of our research on gregarine parasites; provide literature resources, techniques, and protocols to promote gregarine research and the use of gregarines as teaching models; and, promote our vision of a research community that extends beyond the walls of the laboratory and is open to all interested citizens.
Our research is focused on gregarine biodiversity. We're interested in both the discovery of gregarine biodiversity and the evolutionary and ecological mechanisms that enabled both speciation and radiation in this hyperdiverse group. Much of our current work is focused on gregarines parasitizing cockroaches using a three-pronged approach. First, the work is based on biodiversity discovery, including field survey of cockroaches in North America as well as survey of exotic cockroaches to discover and describe both host ranges and new gregarine species. The second prong comprises a molecular approach to systematics and evolution by designing and implementing gene sequence array protocols to reconstruct relationships and evolutionary phylogenies among gregarine species. This both stabilizes the gregarine systematic arrangement and informs patterns of co-evolution between gregarines and their insect hosts. Finally, we are engaged in a series of empirical experiments designed to elucidate mechanisms of gene-pool and species isolation among gregarines.
