Stable isotope measurements of atmospheric gases and aerosols and air-sea exchange.
 

Biography

I joined the School of Environmental Sciences as a Lecturer in Atmospheric Chemistry in January 2006. In 1998, I obtained an M.Sc. degree in chemistry from the Max Planck Institute for Marine Microbiology and the University of Bremen, Germany, with a thesis on "Sulphur isotope exchange and disproportionation of thiosulphate in chemical and microbial systems". In 2002, I received a Ph.D. from the Max Planck Institute for Chemistry and the Johannes Gutenberg University in Mainz, Germany, with a thesis on "Stable isotope measurements of atmospheric nitrous oxide" (advisors: P.J. Crutzen, K.G. Heumann, K. Mauersberger, W. Baumann, C.A.M. Brenninkmeijer, T. Röckmann). Just after my Ph.D., I continued my work on nitrous oxide for six months as a Research Associate with T. Röckmann at the Max Planck Insititute for Nuclear Physics in Heidelberg, Germany. From 2003 to 2005, I worked as a Hess Postdoctoral Fellow in the group of M.L. Bender in the Department of Geosciences at Princeton University, USA, on the development of a membrane inlet mass spectrometer for continuous, shipboard dissolved gas measurements and an analytical technique for on-line isotope ratio mass spectrometry of the triple oxygen isotope composition of nitrate.
