Executive Director, Global Institute of Sustainable Forestry MODS Director MF Program Coordinator Lecturer

Research Overview

My work focuses on land use change, forest fragmentation, sustainable forest management, and U.S. private lands, with a particular emphasis on review and synthesis of scientific research, and making scientific information available to forest managers and conservationists.

I lead the Sustaining Family Forests Initiative, a national coalition aimed at improving the effectiveness of outreach, services and programs for family forest owners, thus enhancing conservation and stewardship of America’s private lands.  For more information, please visit and

The Sustaining Family Forests Initiative is a collaboration between the Yale School of Forestry & Environmental Studies, the U.S. Forest Service, and the Center for Nonprofit Strategies, aimed at gaining and disseminating comprehensive knowledge about family forest owners throughout the United States. The basis of our work is to apply a social marketing approach—the use of commercial marketing techniques to affect positive social change—as a promising means by which to influence family forest owners to take steps to conserve and sustainably manage their land. Since 2010, SFFI has trained over 880 natural resource professionals in landowner outreach. These professionals work in 29 states and represent more than 300 organizations, primarily state forestry agencies and their conservation and stewardship partners.
