Our lab aims to provide conceptual advances in host-pathogen interactions across multiple scales of organization, from within-host processes to community-level dynamics. We apply field, experimental, molecular, modeling, and comparative approaches to diverse study systems, including insect pathogens, avian diseases, bat viruses and mammal parasites. Specific themes we address include: animal movement and infection dynamics; resource subsidies and wildlife health in human-modified landscapes; and macroecology of infectious diseases and global patterns of parasitism. We also study insect ecology, evolution and conservation, especially through our work with monarch butterflies. Our lab maintains a supportive environment that values diversity, creativity, collegiality, and engaging in outreach and education.
