Alex Barron graduated from Carleton College with a B.A. in chemistry and obtained his Ph.D. in ecology and evolutionary biology from Princeton University. Barron's graduate research examined interactions between plants, soils and the atmosphere. In particular, he focused on the patterns and controls of nitrogen fixation in Panamanian tropical rainforests, demonstrating that some trees in the bean family can “tune” their fixation rate across different forest types and that the element molybdenum can limit fixation rates of bacteria in the field.
More recently, Barron has applied his training as a scientist to policy design—first in Congress and then at the Environmental Protection Agency (EPA). In Congress, he worked in both the Senate and House of Representatives to design comprehensive climate legislation (including the American Clean Energy and Security Act) and covered international climate negotiations. At the EPA, Barron worked in the Office of Policy, where he advised senior EPA leadership and worked on a wide range of environmental regulations, including standards to reduce carbon pollution (for example, the Clean Power Plan), cross-state air pollution, and mercury and other toxics. He also helped guide EPA’s work on environmental economics and climate adaptation.
Barron's current research focuses on the design of climate policies to reduce greenhouse gas pollution and avoid catastrophic climate change. This includes evaluating how policies have worked in the past, designing specific policy incentives to reduce emissions, and work to improve the tools that policy makers use when designing those policies. These projects range in scale from national to hyper-local, and he is always looking for interesting collaborations.
His courses include Researching Environmental Problems, Sustainable Solutions and Energy and Climate Policy. In his spare time, Barron enjoys contra dancing, gardening, baking and hiking.
