Popp studies the links between environmental policy and innovation, with a particular focus on how environmental and energy policies shape the development of new technologies for combating climate change. His research often makes use of patent data to trace development of green technologies, exploring how policy and prices shape innovation. Other recent work considers the potential of technology for climate adaptation by studying how innovation responds to natural disasters.

Popp is a co-editor for two journals, the Journal of the Association of Environmental and Resource Economists and Environmental and Resource Economics. He currently serves on the advisory committee of the Green Growth Knowledge Platform. Popp received a B.A. in political economy
