Ecological Risk Assessment
Dr. Johnson's research interests include ecological modeling, risk assessment, and the role of science in informing public policy and decision-making. His teaching focuses on introductory and policy-related courses for undergraduates, and a graduate-level course on ecological risk assessment.
Currently, Dr. Johnson is a Faculty Senator, and serves on the Welfare Committee. He is also the Graduate Program Coordinator for the Department of Forestry and Environmental Conservation.
Ecological modeling, environmental toxicology, and ecological risk assessment, with particular focus on:
• risk assessment and management decisions under uncertainty
• the water-energy nexus
• impacts of water use for electricity on instream biota, including freshwater mussels
• cyanobacteria, their ecology, toxin production, risk assessment and management
