My research interests include conservation genetics, avian ecology and migration, and the conservation of rare and endangered species. Using a combination of field research and molecular genetic techniques I have studied numerous species of raptors (red-tailed hawks, red-shouldered hawks, Swainson’s hawks, Galápagos hawks, sharp-shinned hawks, Cooper’s hawks, great gray owls, merlins) primarily at study sites across North America in collaboration with the Golden Gate Raptor Observatory (http://www.ggro.org). In collaboration with the US Fish and Wildlife Service (http://www.fws.gov/sacramento) I am also studying several species of conservation concern including California clapper rails, vernal pool fairy shrimp, callippe silverspot butterflies, Shasta crayfish, and great gray owls. Current research projects include a population genetic analysis of North American subspecies of merlin, demographic monitoring of great gray owls using passive genetic techniques, and acoustic monitoring of California clapper rails.
