His dissertation examined a range of environmental effects associated with the shale gas boom, including the environmental risks associated with fracking, natural gas transportation policy, and the global carbon effects of U.S. natural gas production. Eyer broadly focuses on the way that market responses to economic conditions will mitigate or enhance environmental risks. His on-going research agenda examines a broad range of climate and risk related environmental issues, including the effect of drought on energy systems and the economic capitalization of risks associated with fracking.
