David is a GIS Research Associate in Global Forest Watch (GFW). Although he works on a variety of research projects, his primary focus has been on how forests store, emit, and sequester carbon globally. Related publications include creating a global model of greenhouse gas emissions and sequestration by forests from 2001 to 2019 at 30-meter resolution, and globally mapping potential rates of carbon sequestration from forest regrowth. David has also contributed to the New York Declaration on Forests annual progress assessment—which tracks global progress in stopping deforestation—since 2018. He is now starting to work on tracking forest fragmentation using remote sensing.

Previously, David was a research fellow at the US Environmental Protection Agency in Washington, D.C., where he worked on national and sub-national climate change adaptation, ecology, and water resource management projects. Prior to that, he was an environmental scientist at the environmental consulting firm Tetra Tech in Atlanta, GA, where he assisted various levels of government with watershed management. In both positions, he used spatial and non-spatial analyses and statistics in partnership with and to support non-profits, several levels of government, other EPA offices, and private businesses.

David received his Bachelor’s degree in Ecology and Evolutionary Biology from Princeton University and his Master’s degree in Ecology from the Georgia Institute of Technology, focusing on the ecology of coral reefs in Fiji. In the year between college and graduate school, he was a research assistant for a coral reef ecology and conservation project in the Comoros Islands.

His favorite activities include learning to play the accordion, fencing (foil), collecting money from countries that don’t exist anymore, and reading novels.
