Field: Systematic and ecological herpetology.
Much of my current research is directed towards the long-term population biology and reproductive ecology of aquatic salamanders.
I am investigating the population structure, activity, and reproduction of a metapopulation of the red-spotted newt
(Notophthalmus viridescens) in a series of abandoned beaver ponds. I have also instituted a research program into
the ecology and conservation status of the eastern hellbender
(Cryptobranchus alleganiensis alleganiensis ). This involves a long-term mark-recapture study of populations of
hellbenders in three streams with different histories of environmental impact as well as a state wide sampling of hellbenders to determine their
overall distribution within Pennsylvania.
In addition I am also working on the reproductive biology of the redbelly snake (Storeria occipitomaculata ) and the
ringneck snake (Diadophis punctatus ). These studies are designed to examine variation in reproductive parameters
within a species due to temporal and geographic factors.
I am also writing a book dealing with the natural history of the amphibians and reptiles of Pennsylvania in conjunction with the Carnegie
Museum of Natural History.
