I am a palynologist (pollen and spores) with expertise in paleoecology, paleoclimatology, and biostratigraphy. My biostratigraphic expertise extends from the Carboniferous to the Holocene, with an emphasis on Euramerica (Paleozoic) and the Northern Hemisphere. My paleoclimate expertise includes the late Paleozoic and the Paleogene to Holocene intervals. Education: University of Illinois at Urbana-Champaign Ph.D., Botany 1990 University of Illinois at Urbana-Champaign M.S., Botany 1985 The Pennsylvania State University B.S., Botany 1982 Stephens College A.A., Geology 1980
