Associate Professor of Biology Emeritus (retired)
William Pfitsch studies how plants meet the challenges of living in potentially stressful conditions. Of particular interest are the interactions with soil microorganisms that help plants meet those challenges. In recent years, research in the Pfitsch lab has also focused on the ecological implications of invasive plants in local forests in terms of community composition and ecosystem structure and function. He earned his doctorate in botany at the University of Washington.
