As Director of the Chemical Sciences Laboratory of NOAA’s Earth System Research Laboratories, I look to advance scientific understanding of three major environmental and societal issues of our time; namely, climate change, air quality and the stratospheric ozone layer, through research on the chemical and physical processes that affect Earth’s atmospheric composition. My personal research interests are focused on measurements of trace gases and aerosols in the troposphere and lower stratosphere and the interpretation of these measurements to advance process understanding and support decision making regarding emissions standards and regulations.
My current interests include
• Assessing of the role of global aviation in climate change
• Leading the 2018 scientific assessment of ozone depletion for the Montreal Protocol
• Leading the Climate Science Special Report for the United States National Climate Assessment
