Research in my lab focuses on amphibian conservation issues. We are currently addressing issues such as invasive species, disease, land use change, and long-term monitoring design for amphibians in North America. We use a combination of comparative surveys and manipulative experiments to understand the factors affecting amphibian distribution and abundance.
