Incumbent is a Research Entomologist in the Systematic Entomology Laboratory (SEL), Beltsville Agricultural Research Center, Northeast Area, with a duty station at the U. S. National Museum of Natural History (NMNH), Washington, D. C. Incumbent’s primary assignment is research on systematics of agriculturally important parasitic wasps of the superfamily Chalcidoidea. This research falls under National Program 304, Crop Protection and Quarantine, Component I, Systematics and Identification, Problem Statement 1A, Insects and Mites. Chalcidoid wasps include both beneficial biocontrol agents and plant pests (~26,000 known, ~500,000 undescribed species worldwide). Incumbent plans and conducts research on taxonomy, phylogeny, biodiversity and biology of chalcidoid wasps, and collaborates and publishes with scientists internationally and nationally. Incumbent is responsible for the identification of chalcidoids and ants submitted by Federal, State and foreign research and action agencies, other researchers, and the general public. The incumbent is curator of the Chalcidoidea collection at the NMNH, consisting of over 700,000 specimens, including over 3,000 primary types. This collection, the largest in the world, is essential for research and identification responsibilities, and is used extensively by researchers worldwide.
