Political economy, Environmental policy, Climate change policy, Energy policy

I conduct research on the political economy of climate change and energy problems. My recent research includes the political economy of energy transitions, regional economic impacts of renewable energy deployment, carbon pricing policy design, and energy technology innovation. Empirically, I am particularly interested in Asian countries such as Japan, China, and India.

Please refer to the following interview article (in Japanese) explaining my recent research on renewable energy technology innovation in China and India.

I welcome students with keen interests in political and economic aspects of environmental problems. The graduate study helps you acquire skills for logically analyzing the problem on the ground with academic theories and research methodologies. I consider it essential that you not only examine “what is going on,” but also contemplate “what can be done” to solve the problem.
