Research Activities and Interests:
My research interests fall at the interface of ecotoxicology, conservation biology, and community, population, behavioral, and disease ecology. I am particularly interested in how anthropogenic changes, mainly pollution and climate change, affect wildlife populations, species interactions, and the spread of disease. These effects are undoubtedly complex and dependent upon biotic and abiotic conditions. Consequently, my collaborators and I have studied interactions among multiple natural and anthropogenic stressors and are making efforts to integrate our research across disciplines. Our goal is to understand, and develop solutions to, environmental problems to enhance the likelihood of a sustainable existence for both humans and wildlife. Much of my research has focused on amphibians because they are declining globally. However, I have worked with a diversity of taxa and I tend to be more motivated by interesting questions, syntheses, and the quest for generalities in ecology and conservation than taxa-specific pursuits. When possible, I try to integrate laboratory experiments, mesocosm studies, field experiments, field surveys, and mathematical models to enhance our understanding of natural systems.
