Director, Forests and Environment Research, Center for International Forestry Research
Louis began his international career as forester in Burkina Faso and in Senegal, working on community-based tree planting, forest management, soil conservation and technical training of national forestry staff. He returned to the US and earned a PhD in forestry at North Carolina State University in 1994. Prior to joining CIFOR, he held positions at the Woods Hole Research Center, the Cary Institute of Ecosystem Studies and the International Centre for Research in Agroforestry. Most of this work focused on developing a better understanding of the nitrogen and carbon cycles in forests to understand how forests and land-cover change are related to environmental problems such as water pollution, acid rain and climate change.
