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 (2011) include:
