Biography

In 2001, I completed my Ph.D. in Oceanography at Scripps Institution of Oceanography, USA. During my thesis work, I developed the world’s first continuous, high precision atmospheric O2 analyser and installed it at the remote monitoring site, Baring Head, New Zealand, where it has continued to collect data uninterrupted since 1999. Atmospheric Omeasurements (together with concurrent COmeasurements) are a relatively new and powerful tool for studying the global (and regional) carbon cycle. For example, we are able to partition and quantify the uptake of fossil fuel COemissions by the oceans and land biosphere, and we are able to monitor changes in the Southern Ocean carbon sink. From 2001-2005, I worked at the Max Planck Institute for Biogeochemistry in Germany, where I was the leader of the “Tall Towers Group”. Here I expanded my work to monitor other greenhouse and greenhouse-related gases such as CH4, CO, N2O, and SF6. We set up multi-species, continuous, automated measurements from very high (up to 300 m) towers in Siberia, Poland, and Germany. Tall tower measurements are a relatively new approach to study regional, terrestrial carbon cycles in continental interiors.

I moved to ENV in 2006 and established the “Carbon Related Atmospheric Measurements” (CRAM) Laboratory as part of LGMAC. With this laboratory, I will bring atmospheric O2 measurement capability to the UK, as well as an additional suite of gases: CO2, CH4, CO, N2 and SF6. I am interested in using these measurements to further our understanding of both the terrestrial and oceanic carbon cycles on regional and global scales. I am currently a P.I. in the EU “CarboEurope” (Assessment of the European Terrestrial Carbon Balance, 2004-8) and “CarboOcean” (Marine carbon sources and sinks assessment, 2005-9) projects. Since 2003, I have been leading an international atmospheric Ointercomparison programme (GOLLUM), which brings together the 12 international atmospheric Olaboratories from around the world in an effort to link our various measurement programmes.
