I am the Executive Director of The Clifton Institute¬†in Warrenton, Virginia. I have a long-standing interest in the ecology and conservation of forests and grasslands in the eastern United States. At the Clifton Institute I direct a program of research on grassland restoration, declining native species, and the effects of urbanization and climate change on biodiversity. I am also a passionate land manager and I work with my team to restore native plant and animal communities on the Clifton Institute’s 900-acre property As an environmental educator I try to get people excited about the lesser known and underappreciated species around us. I also strive to instill an appreciation for the intrinsic value of plants and for their importance for maintaining animal populations.

In addition to my work in the temperate zone, I have a background in research on the effects of the wildlife trade, climate change, and habitat loss on tropical birds, especially in Indonesia, Malaysia, and Ecuador. I believe that strict protected areas are critically important for stopping extinctions around the world. I remain engaged with tropical conservation in my role as a board member for the Jocotoco Foundation.
