Statement of Research:
My research focuses on Pacific salmonids, multiscale aquatic ecosystem assessments over time, effects of disturbances on aquatic ecosystems and native biota, community-based conservation planning, and aquatic biodiversity. I particularly enjoy opportunities to work in multi-disciplinary groups that allow the complexity of the natural world to be more fully represented in research questions and studies. I also serve as the co-chair of the Freshwater Specialist Group for the World Commission on Protected Areas (WCPA), part of the International Union for the Conservation of Nature (IUCN).
Projects & Activities:
Connectivity of Aquatic Habitats Across Space and Time
Disturbance Processes and Native Fishes
Integrated Watershed Management for Restoration,
