ACADEMIC POSITIONS:
1989-1990 Contract consultant USDA, National Museum of Natural History, curation of Pteromalidae and Aphelinidae
1990- present Senior Museum Scientist R.M. Bohart Museum, Dept. of Entomology, University of California, Davis

AWARDS:
1987 Postdoctoral Fellowship, Smithsonian Institution A Taxonomic Review of Nearctic Ormocerini and Pirenini(Hymenoptera: Pteromalidae: Miscogasterinae).

RESEARCH AREAS:
Current research interests focus on completion of a generic revision of the Pteromalidae (Hymenoptera: Chalcidoidea) of the Nearctic region in conjunction with Dr. Z. Boucek (BMNH, London). Species level revisions of many genera of Nearctic Pteromalidae are also underway. Future research projects include work on the pteromalid fauna of Chile.
