Current Research Interests and Projects

Atmospheric Modeling

I just finished my Ph.D. thesis at the Institute of Atmospheric Physics at the Johannes Gutenberg University in Mainz.
In my thesis I investigated the processes during radiation fog events with the 1-dimensional atmospheric model CHEMIFOG_V. My interests are the interaction between the atmosphere and vegetation n the presence of radiation fog, especially the influence of leaf wetness on the atmosphere-biosphere exchange of atmospheric trace gases.

Project Involvement

Research program AFS (Aerosol-Forschungsschwerpunkt) by the BMBF to determine and characterize the physical and chemical properties, the spatial and temporal distribution, and the sources and sinks of the atmospheric aerosol.

Previous Work in Environmental Sciences

Education

• Study of Physics at the University of Osnabrück and the University of Bremen.
• Internship at the Department of Oceanography at the Alfred Wegener Institute for Polar and Marine research in Bremerhaven.
• Diploma thesis (Diplomarbeit) in the group of Prof. John P. Burrows at the Institute of Environmental Physics in Bremen.
• Ph.D. thesis in the group of Prof. Andreas Bott at the Institute of Atmospheric Physics at the Johannes Gutenberg University in Mainz.

Absorption Spectroscopy

• Laboratory measurements of NO₂  absorption coefficients in the UV/Vis.
• Field measurements of atmospheric NO₂  and O₃  with the DOAS group Bremen.
• Investigation of the influence of clouds on DOAS zenith sky measurements - analysis and interpretation of measurements conducted during the SCUVS intercomparison campaign at the Observatoire de Haute Provence, France [see Literature].
• Interpretation of DOAS measurements of enhanced O₃  and NO₂  columns inside thunderstorm clouds with the radiative transfer model GOMETRAN [see Literature].

Chemical Oceanography

• Measurements of the O₂  concentration of sea water samples during the "Polarstern" cruise of the Alfred Wegener Institute for Polar and Marine research to Antarctica [see Literature].

Extracurricular Activities

Ada Lovelace Project

• Since August 1999 I'm working as a mentor in the Mainz group of the Ada Lovelace Project. This project is designed to encourage female students to study in science, engineering or technology fields. Activities enclose visits of school classes at the university, visits of mentors to schools, participation in fares, etc.. For further information please look at the ALP homepage.
