Personal Summary

Born and raised in England, Christopher moved to the United States in the 1990s. He has lived most of those years in the western states where he enjoys mountain biking, skiing, and other activities made possible by the roomy landscapes. 

His research is moved by the idea of the Anthropocene, the epoch in which human influence on the planet is everywhere. He studies emerging Anthropocene technologies for their impact on the human-nature experience. These include climate engineering and biotechnology. His award-winning book The Synthetic Age details some of what is at stake. His current work is on restoration and rewilding. He is finishing a book on wildlife recoveries and what they demand of human-nature relations. The book will be published by MIT Press in early 2023.



Ph.D., University of Oregon (1998)

M.A. (applied ethics), Colorado State University (1993)

B.A. University of Durham, UK (1990)

Research Interests

Rewilding, the Anthropocene, Care Ethics, Ethics of Emerging Technologies, Wilderness, Climate Engineering, Synthetic Biology



I'm currently working on a new book about wildlife recoveries for MIT Press due out in 2022.

The National Science Foundation sponsored some of my research (conducted through the Mansfield Center) on the ethics of geoengineering. As part of that research, I helped create an Online Resource Center for the ethics of geoengineering. The site is no longer updated but it has some useful material on different aspects of geoengineering ethics.  It is archived here.
