Projects per year
In 2001, I completed my Ph.D. in Oceanography at the 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 station, Baring Head, New Zealand, where it has continued to collect data since 1999. Atmospheric O2 measurements (together with concurrent CO2 measurements) are a powerful tool for studying the global (and regional) carbon cycle. For example, we are able to partition and quantify the uptake of fossil fuel CO2 emissions by the oceans and land biosphere, and we can explore oxygen, carbon and heat exchanges between the atmosphere and oceans.
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 UEA/ENV in 2005 and established the “Carbon Related Atmospheric Measurements” (CRAM) Laboratory as part of COAS. With this laboratory, I brought atmospheric O2 measurement capability to the UK. My group also established continuous atmospheric O2 and CO2 measurements at the Weybourne Atmospheric Observatory on the north Norfolk coast in 2008, which is now the longest running CO2 record in the UK. I am and have been a P.I. or co-I. for numerous NERC and EU projects related to improving our understanding of carbon cycle and greenhouse gas science, and their impacts on climate change. Since 2004, I have been leading an international atmospheric O2 intercomparison programme (GOLLUM), which brings together the 11 international atmospheric O2 laboratories from around the world in an effort to link our various measurement programmes. I also manage UEA's "Calibration Cylinder Filling Facility", a facility unique within the UK that provides calibration and reference gases to the atmospheric sciences community.

Key Research Interests
- Improved understanding of global, regional and local greenhouse gas cycles from spatial and temporal perspectives as they pertain to the land biosphere, oceans and atmosphere;
- Development and application of land and ocean observing systems for all major greenhouse gases, related species and related isotopologues (e.g. CO2, O2, CH4, N2O, SF6, CO, Rn, Ar, δ13C-CO2, δ18O-CO2, Δ17O);
- Innovative state-of-the-art technological and methodological developments in very high-precision greenhouse gas measurement;
- Developing new tools, techniques and database products in atmospheric time series analysis;
- Utilising atmospheric greenhouse gas data in regional and global transport models, and in biogeochemical, land-atmosphere and ocean-atmosphere modelling efforts.
