Research interests

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.
