We are hosting our biennial One Health Microbiome Symposium on May 13-14, 2026 at Penn State University (University Park, PA). Registration is currently open, and abstract submissions are open until March 13. "The One Health Microbiome Center at Penn State University invites researchers to the 2026 One Health Microbiome Symposium, May 13-14, 2026. This two-day meeting will bring together evolutionary biologists, microbiologists, ecologists, and computational scientists interested in microbiome dynamics across human, agricultural, and environmental systems. We especially welcome work exploring host-microbe coevolution, microbial community assembly, evolutionary genomics, transmission and adaptation, and the evolutionary consequences of microbiome change in a One Health framework. Keynote speakers include Joy Bergelson, Arturo Casadevall, and Martin Weidmann. The program will also feature trainee talks, poster sessions, workshops, and opportunities for cross-disciplinary discussion.
