image001I am Distinguished Professor Emeritus in Philosophy and Policy, School of Public Policy, Georgia Institute of Technology, having retired from full-time teaching in June, 2014. I continue to be active in research and I still work with a few graduate students in the Georgia Tech School of Public Policy.

I have also been active on boards and study groups. For example, I was a member of the first Environmental Economics Advisory Committee of the US EPA Science Advisory Board, and I served two terms as a member of the Governing Board of the Society for Conservation Biology. I was a member of the Board of Directors of Defenders of Wildlife from 1994-2005 and I’m currently on their Scientific Advisory Board. I made an invited presentation on Synthetic Biology at a meeting of the Presidential Commission for the Study of Bioethical Issues.
