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 chairs the Departmental Curriculum Committee and serves on Departmental Assessment Committee, the Clemson University Sustainability Commission, and committees overseeing the Sustainability and the Astrobiology minors.
My research interests have encompassed ecological modeling, environmental toxicology and risk assessment, landscape ecology, and environmental policy. Currently, I am particularly focused on the intersection of environmental policy and space policy. Specific topics include:
* conceptual issues in astrobiology
* human artifacts in the night sky
* space colonization and closed ecological life support systems
* wilderness preservation and conservation planning beyond planet Earth
