Senior Scientist, Sustainability Science
Sheila Walsh Reddy is a senior scientist with The Nature Conservancy's Sustainability Science Program. Sheila's research focuses on how ecosystems and economies are interrelated and how to improve environmental decision making. The results of Sheila's research supports the Conservancy's mission by helping to identify and test conservation strategies that benefit both people and nature.
Currently, Sheila is developing methods to incorporate the value of nature into business decision making through a collaboration with The Dow Chemical Company and Foundation. Sheila is also investigating how to align marine management institutions, from local fishing cooperatives to national policies, with key ecological and economic factors in Mexico.
Sheila has previously conducted research on marine ecology, conservation and economic development issues in Kiribati, Mexico, Belize, and the USA. In addition to publishing in scientific journals, Sheila's research has been featured on media outlets, such as NPR and Change.org, and has helped inform governments, NGOs, and local stakeholders.
Sheila previously was a postdoctoral research associate in the Department of Economics and the Department of Ecology and Evolutionary Biology at Brown University. In 2009, Sheila received her Ph.D. from the interdisciplinary program in Marine Biodiversity and Conservation at Scripps Institution of Oceanography in partnership with the Department of Economics, University of California-San Diego.
Sheila's research focuses on ecosystem services. She works to design and test incentive-based conservation strategies that have outcomes for people and nature.
Her research areas and questions include:
Sheila is answering these questions through research in the U.S. with the Dow Chemical Company and in Mexico and Kiribati with academic partners at Brown University, Scripps Institution of Oceanography, and University of Victoria.
In addition to publishing in peer-reviewed journals (see publications tab), Sheila has written numerous essays and been interviewed by a variety of media outlets about her research:
