Interests and Expertise

I am interested in all aspects of aquatic insect biology, especially the resolution of species using genetics, reproductive biology, and life history data. I have also combined my interests in entomology and photography to produce a large collection of images of aquatic insects in their native habitat.

Photography

I have been taking pictures of insects for more than 30 years and have developed special equipment such as a shallow underwater rig (pictured below) for taking in-stream photos aquatic insects. My photographs have appeared in numerous books and magazines, including Natural HistoryScientific AmericanRanger RickNational WildlifeWings (Xerces Society), BBC Wildlife, and Nature Australia.
