Beetle systematics. Staphylinid beetles are one of the greatest successes of evolution.
With more than 55,000 described species,
they are found virtually everywhere and have a plethora of forms and evolutionary novelties. Even though staphylinid beetles are
numerous, they have received relatively little attention. I am involved in several research projects dealing with both systematic
questions (description of new species, phylogenetic analyses and monographs) and broader evolutionary questions such as the
evolution of coloration, of eye size and the diversification of major lineages. Current project include: a) Phylogenetic revision of
the subtribe Xanthopygina. b) Species-level revisions of Xanthopygina. I currently working on the genus Trigonopselaphus and
future projects include the genera Xanthopygus, Oligotergus, Gastrisus, Phanolinus, Plociopterus and Styngetus. The overall goal
of this project is to produce species-level revisions for all neotropical Xanthopygina genera,
Tennessee Valley Beetle Fauna. Recently we have started a project to catalogue and
identify the beetles in the TN valley region
and the Cumberland Plateau. Simple questions such as: "How many species of beetles are there in TN?" or "What is the
conservation status of beetles in TN?" are without an answer.
Fossil Insects. I am interested in describing fossil insects and investigating how
these discoveries affect the phylogenetic
relationships of extant taxa. Past projects include the description of Oxytelinae from Dominican amber and of several enigmatic
Scydmaeninae from the early Cretaceous. I am currently describing the Staphylinidae fauna from Dominican amber and I plan
to continue my paleoentomological studies with several new enigmatic genera of Staphylinidae from Burmese amber and the
Green River Formation that will help us delineate the tribes and eventually understand the paleobiogeographic history of
