With colleagues at Carnegie Mellon University, he is working on a project titled Air, Climate and Energy (ACE) Center: Science Supporting Solutions. The goal of this research is to explore the interface between air pollution, climate change and energy use. With colleagues at the University of California-Davis, he is working on a project titled Optimal Energy Portfolios to Sustain Economic Advantage, Achieve GHG Targets, and Minimize PM2. This research explores air pollution, climate change, and economic activity in California. These grants provide salary funding for his 17-18 academic leave and summers for the next three years.
