My earliest research was on dragonflies (Odonata) in Missouri, and this resulted in later research opportunities in Thailand (see pubs.).

My masters at the University of Missouri was chiefly a survey of the Mayflies, Stoneflies, and Caddisflies (Ephemeroptera, Plecoptera, and Trichoptera) of Missouri State Parks (see pubs.).

Presently my research is centered on beetles in rotting wood (saproxylic Coleoptera) and other ventures of interest (Neuroptera; Diptera (amazingly), etc.). See below for publications on completed projects.
