My research on host-pathogen interactions and the sustainability of marine ecosystems has taken me from the reefs of Mexico, Indonesia, and Hawaii to the Pacific Northwest. The current focus of my laboratory group is on sustainable marine biodiversity and the ecology of host-pathogen interactions in a changing ocean. A sub-theme of this work includes evaluating the impacts of a warming climate on marine ecosystems. My analyses and papers have led to the now widespread acceptance that diseases are restructuring marine ecosystems, from very climate-sensitive coral reef ecosystems to rocky temperate shores. Projects in my lab involve multi-disciplinary, cross-scale approaches, including field studies, remote sensing, genetic and transcriptomics, chemical analyses, and mathematical modeling. I lead an NSF Research Coordination Network on Ecology of Infectious Marine Disease.
