I am studying the population dynamics of Cascades frogs in the Klamath Mountains and southern Cascades of California in relation to the amphibian disease, chytridiomycosis. We are using observations, field experiments and lab experiments to determine the effects of the disease on the frogs and to find ways to allevitate those effects. I also have initiated a research program to study the effectiveness of meadow restoration projects in improving conditions for biodiversity and ecosystem adaptation to climate change.
I specialize in applied research directed toward the conservation of amphibians and reptiles, especially in mountain environments. However, many of my projects also address key basic concepts in ecology like the role of ecosystem subsidy in supporting wildlife populations and how population dynamics are affected by pathogens.
