His research is focused broadly on anthropogenic carbon flows and the ways that CO2 is manipulated, reused, and sequestered in engineered systems. The results of his work are important for developing efficient strategies for mitigating the emissions that are driving climate change. At the largest scales, his system-level modeling work has explored the life cycle of systems in the manufacturing, transportation, and energy sectors. In the laboratory, he is pursuing complementary research in the phase behavior and surface chemistry of carbon dioxide mixtures at high pressure.
