I am an Associate Professor at the [Johns Hopkins School of Advanced International Studies (SAIS)](https://www.sais.jhu.edu/) in Washington, DC. My research interests lie in comparative political economy, at the intersection of climate policy, environmental politics, and economic and industrial policy. Clean energy transitions—the move away from fossil fuels for instance through the use of renewable energy and the electrification of the global auto sector—are changing domestic and international politics in real time. Against this background, my research uses the analytical tools of political science to examine what drives such state responses to climate change and to identify political obstacles to government attempts to decarbonize domestic economies. Specifically, my work builds on insights from comparative politics and comparative political economy to study how economic coalitions—and the actions of firms in particular—structure the dynamics of clean energy transitions. At the same time, my research takes advantage of such transitions as especially useful laboratories to build and refine theory, as they bring together rapid technological change, interest group conflict between emerging industries and legacy sectors, and degrees of state intervention in the economy rarely witnessed outside of the context of late industrialization.  My research agenda now spans three separate but interrelated strands: (a) green industrial policy and the drivers of the division of labor in the global economy, (b) sources of state capacity to overcome external opposition to clean energy transitions and climate policy, and (c) the political economy of green growth. My book *[Collaborative Advantage: Forging Green Industries in the New Global Economy](http://www.jonasnahm.com/book.html)* (Oxford University Press 2021) examines the development of the wind and solar industries, two historically important sectors that have long been the target of ambitious public policy.
