A.R. Siders is an Environmental Fellow at the Harvard University Center for the Environment. Siders' research focuses on climate change adaptation governance, exploring how institutional and social structures affect decisions around adaptation policies and how those policies affect social justice and risk reduction outcomes. She combines approaches from hazards geography, sociology, law, digital humanities, and computational social science. Siders also collaborates with consulting companies and non-profit organizations to integrate climate change adaptation into disaster risk reduction and resilience efforts. Her work spans several geographic regions, including infrastructure development in the Arctic, coastal defense in the United States, and urban resilience in Europe and South-East Asia.

Siders previously served as a Presidential Management Fellow with the U.S. Navy, where she worked on clean energy, science cooperation, and international engagement and capacity building in Africa. She was also an Associate Director of the Center for Climate Change Law at Columbia University, where she worked on post-Hurricane Sandy recovery. She is a research fellow with the Earth Systems Governance Program, Florida Earth Foundation, Earthquakes and Megacities Initiative, and the Hoover Institution Arctic Security Initiative. She holds a J.D. from Harvard Law School and a Ph.D. from Stanford University. She is originally from Duluth, Minnesota, and misses the cold.
