Research Interests

I am a systematist with research interests ranging from phylogenetic reconstruction, historical and ecological biogeography, biodiversity measures and evolution of morphological character systems. My systematic expertise is in insects, specifically crane flies (Tipuloidea), an insect group of nearly 16,000 described species worldwide found in a wide range of aquatic and terrestrial habitats.

Current research projects include: inventory and endemism of aquatic insects in Mongolia (http://clade.acnatsci.org/mongolia/; the evolution of crane flies in the deserts of western North America and its application to understanding the historical biogeography of these regions; development of identification keys for larval and adult crane flies in the New World; crane fly communities of the Atlantic Coastal Plain, focusing on the New Jersey Pine Barrens.

 

Current Funded Projects (2014) include:

  • Survey and Inventory of the Aquatic Insects of the Altai and Hangai Mountains’ drainages, Mongolia. $720,000. (with J. Morse, C. R. Nelson), NSF: Biodiversity Inventories (DEB-0743732), FUNDED for 2008-2012. http://clade.ansp.org/entomology/mongolia/mais_about.html
  • A digital species index to The Academy of Natural Sciences’ Entomology Collection. $150,000. IMLS-Museums for America, MA-05-10-0001-10. FUNDED Oct. 2010-Sept. 2014.
  • Renovation of the Academy of Natural Sciences’ Entomology Department Research Collection & Associated Lab. $1,051,265. (with D. Otte). NSF: DEB: Academic Research Infrastructure (ARI). DBI-0963474. FUNDED Oct 2010-Sept. 2014.
  • Aquatic crane fly diversity and seasonality in the Chesapeake Watershed: sampling along a transect from estuarine to freshwater.  $26,000.  ANSP ERC.  FUNDED 2014.
