I grew up in the Columbus, Indiana, area and have returned to this community. Currently, my students and I investigate various topics in environmental science, especially those related to freshwater insects. These organisms have proven valuable for the development of new generation identification systems, the analysis of biodiversity patterns in space & time, and the application of phylogenetic models to problems in environmental toxicology. Much of my research has focused on the insect order Ephemeroptera, or mayflies. Aspects of this research include, but are not limited to, taxonomy and identification, DNA barcoding, biodiversity, phylogeny, rearing and stage associations, descriptive biology and ecology, field studies, conservation, species inventories and regional faunistics. I interact with various international stakeholders in the academic, government and private realms.
