As the senior scientist on the WWF-US Sustainable Infrastructure team, Tremaine Gregory collaborates with experts, companies, financial institutions, and governments to encourage the adoption of environmental safeguards in infrastructure development. These safeguards aim to change how infrastructure is planned, built, and operated so that new infrastructure has a limited impact on nature; natural infrastructure is maintained and well managed; and all infrastructure serves to conserve or restore nature, increase resilience, and mitigate climate change.

Tremaine plays a significant role in the U.S. Agency for International Development (USAID)-funded project Asia’s Linear Infrastructure safeGuarding Nature, which WWF is implementing with the Center for Large Landscape Conservation. The project aims to expand the development and implementation of effective, high-quality linear infrastructure safeguards in Asia—focusing on India, Mongolia, and Nepal. She also contributes to the Taskforce on Nature-related Financial Disclosures (TNFD), of which WWF is a founding partner. Tremaine is helping the TNFD develop a framework for the infrastructure sector to assess, manage, and report on its dependencies and impacts on nature.

Tremaine brings a wealth of knowledge and experience to WWF. During her 12-year tenure at the Smithsonian’s National Zoo and Conservation Biology Institute, Tremaine focused on sustainable infrastructure development. While there, she used her expertise to develop strategies to minimize the negative effects of transportation and energy infrastructure on delicate ecosystems like the Amazon and Paraguay’s Atlantic Forest.

She also specializes in researching arboreal mammals. Tremaine pioneered camera trapping techniques in the high tree canopy and developed several canopy bridge studies to assess how these bridges can increase habitat connectivity for arboreal mammals.

Tremaine holds a master’s degree and a doctorate in biological anthropology from Kent State University in Ohio.
