David Bunn

David Bunn, PhD, is an ecologist, policy expert, international consultant, and One Health advocate who has spent decades working at the intersection of human health, animals, food systems, the environment, science, and public policy. His career has taken him from fieldwork in Africa to leadership positions in California government and international development. Drawing on this unusually broad perspective, Bunn examines human health as an ecological system shaped by evolution and increasingly disrupted by modern life. In Health Basics for a Mismatched World, he translates that perspective into a practical framework for understanding the roots of chronic disease and taking greater control of lifelong health.
