Michael L. DeKay

Professor DeKay is interested in judgment and decision making, particularly in the environmental and medical domains. His current research projects involve perceptions of ecological risks; ranking health, safety, and environmental risks; precautionary reasoning; and the perceived fungibility of outcomes in repeated decisions. He is a member of the National Research Council's Panel on Public Participation in Environmental Assessment and Decision Making.
