Stephanie Siehr


Program Director
Full-Time Faculty


Professor Siehr works on energy–based solutions to multiple environmental problems–from local air pollution to global climate change–combining engineering with tools from political economy and organizational analysis. With a geographical focus on China, Japan, and the US, her research and teaching examine energy and carbon saving strategies; emissions inventories; city climate action; environmental and energy policy analysis; urban sustainability, international cooperation; and environmental risk management.
