Biographical Statement

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.

Research Activities

Mayflies are thought to be the oldest extant group of winged insects. What stories they must have to tell! Little by little, we are piecing together their part of the Earth's natural history. To get the full picture, we will need to answer several questions. Which species are here? What do we call them? Where do they live? How do they function? How do they interact? Gathering information about species' geographic distributions, biologies and morphologies (from external body structure to DNA sequence) will help answer these basic questions. Of further importance, mayfly species are commonly utilized worldwide as indicators of environmental health and are often the subjects of ecological and physiological studies.
