Prof. Toohey's research addresses the role of trace gases and aerosols on Earth's climate, atmospheric oxidation, and air quality. He develops instruments for fast-response in situ measurements from the ground, balloons, and aircraft. He has participated in numerous field campaigns to study topics such as stratospheric ozone depletion over the Arctic, the impact of rockets on stratospheric chemistry, long-range transport of pollutants, and the role of aerosols in modification of cloud properties. He has conducted work in Antarctica, Spitsbergen, New Zealand, Sweden, Nepal, the Virgin Islands, Alaska, Hawaii, and throughout the continental United States.

During the 2011-2012 academic year, I served as a Jefferson Science Fellow at the U.S. Department of State in the Bureau of East Asian and Pacific Affairs.  I worked on issues related to energy and green growth for APEC, attended the 10th  APEC Energy Ministerial Meeting in St. Petersburg, Russia, and organized an APEC Workshop on Climate Change Adaptation in Singapore.  In Fall 2012 I will be teaching a new course on Climate Change, Energy, and Foreign Policy loosely based on my work as a science fellow. A video of my lecture at the Dept. of State on the relevance of the stratosphere can be found here.
