My group’s research helps improve our understanding of the sources and sinks of greenhouse gases. We study the changes in atmospheric composition happening now and the changes that have occurred over the last few decades. We are 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.
My primary work place is at Lund University
Current work
1) Developing in situ, high precision measurements of methane isotopologues
2) Maintaining and interpreting high precision long term measurements for greenhouse gas emissions estimates on regional scales
3) Inverse modelling to understand sources and sinks of greenhouse gases on global and regional scales
4) Methods to understand industrial emissions at source
Biography
Since 2024 I work at Lund University (Sweden) and at the University of Edinburgh. In 2016 I joined the University of Edinburgh in a joint position with the National Physical Laboratory. Between 2014 and 2016 I was at the Met Office Hadley Centre. Prior to this, I spent more than five years in the USA at the University of California, San Diego at the Scripps Institution of Oceanography as a postdoc studying atmospheric composition change (2009-2014). My undergraduate studies were in Natural Sciences at the University of Cambridge (2001-2005) and I followed this with a PhD in isotope geochemistry in the Earth Science and Engineering Department at Imperial College London (2005-2009).
