My research group strives to be a world leader in the measurement of volatile organic compounds and the interpretation and synthesis of these measurements in the full context of atmospheric chemistry. A main goal of my research activity is to participate in collaborative efforts to quantify the chemical composition of the atmosphere, characterize how it is changing in response to natural and anthropogenic forcings, and, ultimately, develop the capability to predict changes that may have important implications for the health of the Earth’s ecosystem. I have acquired expertise in the development and deployment of novel instrumentation to measure a suite of volatile organic compounds (non-methane hydrocarbons, oxygenated volatile organic compounds, and CFCs and HCFCs) that directly impact the chemistry of the troposphere and lower stratosphere. I place a special emphasis on the interpretation of these measurements with respect to their impact on cycles of NOx, HOx and halogens. I have led the development of the unique and highly successful Trace Organic Gas Analyzer (TOGA). TOGA quantifies a full suite of the VOCs listed above in near-real-time at unprecedented levels of accuracy, precision and speed on multiple platforms, including the NCAR GV, and C-130 aircraft, as well as the NASA DC-8. Recently I led the development of the Trace Organic Gas Analyzer - Time-of-Flight Mass Spectrometer (TOGA-TOF). This is the most advanced Fast GC-MS TOF instrument in the world. It was recently deployed on the NASA DC-8 for the FIREX-AQ mission. I recently led the development of the WASPP – the NCAR ACOM Whole Air Sampler Pilotless Platform, a unique and versatile atmospheric sampling drone system developed during Lizzy Asher’s ASP Postdoc.

My research helps improve our understanding of the sources and sinks of greenhouse gases. I study the changes in atmospheric composition happening now and the changes that have occurred over the last few decades. I am especially interested in the development and use of high-precision ground-based measurements that are sensitive to gas fluxes on local to regional to global scales. Sources and sinks can be quantified from these measurements using atmospheric transport models within a mathematical inversion framework. Developing novel measurement methods and improving the quality of information within this framework holds promise to reduce emissions estimate uncertainties, and most importantly, help focus climate change mitigation efforts.
