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 serves on the Departmental Assessment Committee, the College Committee on Teaching and Learning, the Clemson University Sustainability Commission, and committees overseeing the Sustainability and the Astrobiology minors. He is also Chair of an ad hoc committee to re-write the College bylaws.
Ecological modeling, environmental toxicology, and ecological risk assessment, with particular focus on:
* risk assessment and management decisions under uncertainty
* the water-energy nexus
* conceptual issues in astrobiology, including space colonization, terraforming, wilderness and conservation planning beyond planet Earth
