Sheila Walsh Reddy

Behavioral Economist, The Nature Conservancy

Sheila is a Behavioral Economist at The Nature Conservancy (TNC). Her research focuses on understanding and transforming private practices and public policies in order to make conservation a regular part of how people live and work.

Through TNC’s collaboration with The Dow Chemical Company, Sheila has been part of a team that is developing new methods, tools, and goals for businesses to value nature in their decisions. The defining success of this work is Dow’s Nature Goal – a first-ever commitment by a corporation to consider nature in virtually all of its business decisions and deliver $1 Billion in new value by doing so. Sheila is now the TNC lead for the pilot to test the Nature Goal process – a corporate-wide process that aims to provide a blueprint for Dow and other corporations to value nature. Beyond the TNC-Dow Collaboration, Sheila has worked with teams of interdisciplinary scientists and practitioners to bring economic and behavioral insights into projects related to coastal protection, fisheries, agriculture, urban conservation, and conservation professionals' practices.

Prior to joining TNC in 2011, Sheila was a Postdoctoral Researcher in the Department of Economics and the Department of Ecology & Evolutionary Biology at Brown University. Sheila received her Ph.D. in Marine Biology from Scripps Institution of Oceanography through an interdisciplinary program with the Department of Economics at University of California-San Diego. She holds a B.S. in Biological Sciences from Stanford University.

Sheila is a Behavioral Economist at The Nature Conservancy. Her research focuses on understanding and transforming private practices and public policies in order to make conservation a regular part of how people live and work.

Through  TNC’s collaboration with The Dow Chemical Company, Sheila has been part of a team that is developing new methods, tools, and goals for businesses to value nature in their decisions. The defining success of this work is Dow’s Nature Goal – a first-ever commitment by a corporation to consider nature in virtually all of its business decisions and deliver $1 Billion in new value by doing so. Sheila is the TNC lead for the pilot to test the Nature Goal process, which aims to provide a blueprint for other corporations to value nature.

Beyond the TNC-Dow Collaboration, Sheila has worked with teams of interdisciplinary scientists and practitioners to bring economic and behavioral insights into projects related to coastal protection, fisheries, agriculture, urban conservation, and conservation professionals' practices. This work has highlighted the importance of behavioral and institutional factors, as opposed to purely ecological and economic factors, in decisions related to climate risk reduction and resilience, coastal protection, and fisheries. The results have helped identify new ways to influence positive behavior change using market mechanisms, state policies, local institutions, demonstration sites, leaders, and social norms.

In 2014, Sheila was named a New Horizons in Science Fellow by the National Academy of Sciences. She has over 20 publications, including one that was recommended by the Faculty of 1000. The TNC-Dow Collaboration received the Roy Family Award for Environmental Partnerships in 2013 and the Alliance for Corporate Social Responsibility Award in 2015.

Prior to joining TNC in 2011, Sheila was a Postdoctoral Researcher in the Department of Economics and the Department of Ecology & Evolutionary Biology at Brown University.
