BIOGRAPHICAL SKETCH I was born and raised in Des Moines, Iowa. I obtained a B.S. in chemistry, with concentrations in biology and math, from Clarke College, Dubuque, Iowa. My M.S. in biochemistry, investigating structural and kinetic properties of aldehyde dehydrogenase isozymes, was earned at Purdue University in the laboratory of Henry Weiner. I then worked at Rainbow Babies and Children's Hospital, Case Western Reserve University, Cleveland, Ohio, developing an animal model for studying pediatric giardiasis. When the grant money ran out, I was fortunate to obtain a position studying gene expression in central nervous system tumors with Tim Mapstone, M.D., Department of Neurosurgery, and Dave Goldthwait, M.D., Department of Biochemistry, CWRU. Recognizing that I was more interested in teaching and conducting entomological than medical research (and that I would rather be warm than cold), I called H. Glenn Hall, at the University of Florida, to inquire about the possibility of working toward my doctorate in his laboratory (i.e., I invited myself into his lab). I have met an outstanding group of people at UF, had terrific opportunities to travel and teach, and have enjoyed great freedom in conducting my research. 111
