I study the conservation biology, behavioral ecology, and population and community ecology of amphibians and reptiles, and selected other taxa. My current projects address: 1) the effects of forest management practices and riparian buffer widths on headwater habitats and species; 2) microhabitat- to landscape-scale habitat modeling, including the effects of climate change on species and habitats; 3) development of data management and mapping portals for amphibian and reptile diseases; and 4) context matters for amphibian infection by the chytrid fungus Batrachochytrium dendrobatidis.  Recently, I have been working on a variety of syntheses with an amazing group of partners -- for western forests and their management, aquatic invasive species, aquatic biodiversity, and amphibian research and conservation priorities. I also serve in a variety of roles:  Team Leader - Aquatic Ecology and Management team, US Forest Service, PNW; Courtesy faculty, Oregon State University; Associate Editor, Diseases section of Herpetological Review; USA regional lead for the IUCN SSC Amphibian Specialist Group; Bsal Technical Advisory Committee; US federal Northwest Forest Plan Intermediate Management Group for Survey and Manage; and IUFRO Division 8, Aquatic Biodiversity lead.
