Dr. Johnson's research interests include ecological modeling, risk assessment, and science-based environmental 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 the Graduate Program Coordinator for the Department of Forestry and Environmental Conservation, and serves as chair of the departmental curriculum committee.
Ecological modeling, environmental toxicology, and ecological risk assessment, with particular focus on:
• risk assessment and management decisions under uncertainty
• the water-energy nexus
• freshwater mussels
• conceptual issues in astrobiology, especially wilderness beyond planet Earth
