Research Interests

My research centers on the natural history and systematics of stream-associated beetles in Latin America. Much of the field work involves collecting in areas where stream beetles have not yet been studied. After assembling sufficient material I develop identification keys, usually down to the generic level, so that in-country workers can conduct their own studies. Additionally I maintain an extensive, on-line, worldwide bibliography of aquatic and semiaquatic byrrhoid beetles, the usual stream-associated beetles.
