My research program has recently focused on four major research areas:

  1. Research on China with a focus on potential co-benefits for air quality, health and carbon dioxide mitigation of increased penetration of renewable energy/electrification, and trade-offs with the use of natural gas and synthetic natural gas;
  2. Opportunities to mitigate agricultural and health damages in China via changes in both agricultural production and dietary consumption practices;
  3. The role of Chinese overseas foreign investment and development investment in increasing global utilization of coal powered electricity generation; and
  4. Field investigation of methane leakage from abandoned oil and gas wells in Pennsylvania and West Virginia, as well as from North Sea oil platforms.

My group has developed substantial expertise on energy-environmental issues in China. Our technical analyses have helped inform policy development in China. We will continue to explore the role of China in overseas development of the power sector and explore opportunities to leverage air pollution mitigation strategies in China to reduce greenhouse gas emissions domestically. We also plan to expand our research to work in India, particularly leveraging our existing experience in identifying co-benefits for air quality, health and climate in China and applying it to the Indian context, as well.


Interdisciplinary Approach

Scientific analysis is a vital prerequisite to the development of sound environmental policy responses in the above areas. Rarely will an atmospheric scientist venture into the policy arena and rarely will a policy maker understand the details of atmospheric science. Research frequently remains within a single discipline. However, in order to address the deleterious effects of air pollution on climate change, human health, and welfare, to examine the costs imposed on society by these effects, and to explore energy technology and policy options for encouraging more desirable outcomes, interdisciplinary research is critical.

My group’s research, together with our collaborators, maintains depth in atmospheric science and utilizes tools from public health, agronomy, engineering and economics to inform the development of appropriate environmental policy. Our research to date has made significant interdisciplinary contributions and has laid an unusually strong foundation to address further questions at the intersection of atmospheric science and policy.
