Currently Comstock is professor of philosophy and director of the ethics program at North Carolina State University. He is the author of an influential book on agricultural biotechnology, Vexing Nature? On the Ethical Case Against Agricultural Biotechnology (2000), in which he explains his transformation from writing essays against genetic engineering, to becoming a "cautious proponent" of GM foods. In addition, Comstock is the current editor of Life Science Ethics and is a world-renowned expert in ethics.
Comstock's presentation is the fourth talk in the series The Environment in Crisis, sponsored by a grant from the Andrew W. Mellon Foundation, the Roberts Environmental Center, and the David E. French Lectureship.
