RESEARCH

  •      Systematics of Mutillidae with emphasis on the nocturnal Southwestern Nearctic genera
    Current research includes systematics and biogeography of the nocturnal genera Odontophotopsis and Sphaeropthalma s.l., as well as the diurnal genera Lomachaeta and Dasymutilla.
  •      Systematics of spider wasps (Hymenoptera: Pompilidae)
    Currently I am working on a comprehensive phylogeny of Pompilidae, deriving data from morphological, behavioral, and molecular sources, in attempts to validate subfamilial and tribal classifications. Ultimately my goal is to provide tests of hypothesized evolutionary behavioral scenarios of spider wasps in a phylogenetic context.
