B.S. Entomology, 1990. Mississippi State University

I began collecting butterflies and insects as a high school student living in the Canal Zone of Panama, back in 1973. Dad was in the army and we were immersed in the splendor and diversity of the tropics.  My interest in butterflies and insects has persisted.  I see my work as a professional botanist as just another aspect in the study and appreciation of nature and concern for conservation. I have collected in Tamaulipus and Baja California Sur in Mexico, Costa Rica, Panama, Tambopata, Tarapoto, and Iquitos, Peru, Rondonia, Brazil, and various parts of the Southeastern United States.
