Travis’ work tends to fall into one of two, quite distinct research programs. The first concerns ethics and policy questions about sustainability and planetary limits. Much of this research has been on issues in climate change ethics and procreative ethics with a particular focus on the intersection of the two – that is, on the question of responsible procreation in the era of climate change.  His publications have appeared in several journals on this topic, as well as in a short book with Springer, entitled Toward a Small Family Ethic (2016). He also works on food ethics related to climate change and sustainability, and is currently a member of the Global Food Ethics and Policy team, focusing on ethical issues concerning high-emissions food, in particular animal-sourced foods.

The second, and much newer, research program concerns ethical and policy issues surrounding America’s opioid epidemic. In this area, Travis has published an essay in Health Affairs concerning physician responsibility for safely weaning patients off prescription opioids, and co-authored a National Academy of Medicine Perspective Paper on Physician Responsibility in combating the opioid crisis.

In addition to his more scholarly writing, Travis is firmly committed to doing bioethics with the public, and to that end writes and interviews regularly for the popular media; his work has appeared in very many high-impact publications, including The Guardian, Washington Post, NPR’s All Things Considered, New Republic, and IFLScience. He writes regularly for The Conversationand blogs occasionally at The Huffington Post and the Berman Institute Bioethics Bulletin.
