Keynyn Brysse

Research Associate

I study the history and philosophy of paleontology, and I am particularly interested in how scientific knowledge travels across disciplinary boundaries. My master's thesis explored the reaction of vertebrate paleontologists to the hypothesis that a bolide impact caused the Cretaceous-Tertiary mass extinction 65 million years ago. An article describing this research was published in a November 2003 issue of USA Today. My Ph.D. dissertation examines the recent reclassifications of the 505-million-year-old Burgess Shale organisms, and their implications for scientists' understanding of the diversity of life and the operation of evolution.

I am working jointly with Michael Oppenheimer at STEP, and Naomi Oreskes at UCSD, on a project which explores the history of scientific assessments of ozone depletion and their implications for public policy.
