I am part of the IM4CA (Investigating Methane for Climate Action) project. In this role, I analyze stable isotopes, as well as multiple substituted isotopologues (clumped isotopes) in atmospheric methane in order to study its sources and sinks. In addition, I am also proficient in the analysis of stable isotopes and multiple substituted isotopologues in atmospheric CO₂. I am an expert in isotope ratio mass spectrometry.
