Graduate Students

Christopher Callahan, Systematics and Biogeography of Whales and their Ectoparasites
Christopher is using analysis of DNA and museum specimens to examine how whale lice (crustacean ectoparasites) made the evolutionary jump to colonize gray whales.

Erin Atkin, Molecular Ecology of River Otters
Erin is using DNA data obtained from scat samples to investigate patterns of dispersal in river otters of northwestern California.

Nick Kerhoulas, Systematics and Biogeography of Mesoamerican Flying Squirrels
Nick is using DNA data obtained from skin samples of museum specimens to examine the evolutionary relationships and biogeographic history of flying squirrels from the highland forests of Mexico and Central America.
