John Toll

John is a chemical and environmental engineer with a doctorate in Engineering and Public Policy. He specializes in investigating physical and chemical habitat alterations that might disrupt ecological processes, damage natural resources, or impair human health. He finds ways to improve how science and technology inform environmental policy, planning, and management decisions, thereby reducing the needed margin of safety in management decisions and freeing up resources for other, more useful endeavors. Dr. Toll’s 35 years of professional experience have helped him become adept at recognizing how people perceive environmental problems, how to utilize his technical expertise to help individuals re-examine their perceptions, and how to harness his skills to help people derive mutually acceptable solutions to contentious problems. Dr. Toll has authored numerous peer-reviewed publications. He serves as a deputy editor-in-chief of Integrated Environmental Assessment and Management and is a founding member of the International Board of Environmental Risk Assessors, an accreditation board created in 2020. He is a past president of SETAC North America.
