My interest in insects became obvious early on when I started culturing moth and butterfly caterpillars in my room as a boy. This, as it turns out, was the beginning of a career in comparative biology with a focus on insects, their eyes, their genomes, and genes. I earned my PhD degree from the Department of Zoology at the University of Munich in 1995 and joined WSU in 1999 after 3 years of postdoctoral training at the California Institute of Technology.
Research Interest/Area of Expertise
My lab explores the developmental evolution of the insect visual system integrating molecular phylogenetics, comparative development and genomic approaches. Our animal models in the lab include the red flour beetle Tribolium castaneum and the small carrion cave beetle Ptomaphagus hirtus.
