(Johnson, Pieter - 2008) -- Fellowships for Science and Engineering
Professor Johnson’s research focuses on two pervasive and inter-related forms of biological change: disease emergence and species invasions. Both have important consequences not only for individuals and populations but also for entire ecological communities and ecosystem processes. Invasions and disease have costly economic and health repercussions for human societies. Professor Johnson’s current research program is directed toward three interrelated areas: cross-scale drivers of disease emergence; the functional role of disease in ecosystems; and interactions among invasions and habitat alteration. All have immediate relevance to both fundamental questions in ecology and applied conservation issues. Using long-term data, ecological experiments, and modeling approaches, Professor Johnson examines the factors that drive disease emergence and biological invasions to understand how changes in disease and invasion levels affect community interactions and ecosystem processes in aquatic environments. He has been a member of the CU-Boulder faculty since 2007.
