Research Interests: Within the Atmospheric Chemistry Group at the University of Wuppertal, I am currently working on the following research topics: Atmospheric Chemistry Field Measurements and Laboratory Investigations. Photochemical Modeling
Explicit photochemical modeling analysis of the radical budgets and ozone photochemical formation in the atmosphere, mainly based on the Master Chemical Mechanism, MCM.
Combustion Chemistry Laboratory investigation of the emission profiles from the combustion processes in Jet-engine using a premixed (laminar flame) burner and their impact on the atmosphere (e.g., their potential to ozone formation).
Current Research Projects • International FIONA Measurements campaign at the EUPHORE -smog chamber in Valencia-Spain for the validation of different HONO measurements techniques, Valencia, Spain. Status: Data evaluations finished, results discussion and publications will follow.
• International ECATS (Environmental Compatible Air Transport System) project to investigate the emissions from different newly developed Jet-engine fuels and to determine their impact on the atmosphere. Status: Campaign in progress
Previous Research Projects 10.10.04 - 21.10.04 • Measurements campaign in EUPHORE (European photo reactor)-smog chamber in Valencia-Spain for the evaluation and validation of new developed HNO3 LOPAP instrument. Status: Finished and published. 16.01.05-30.01.05 • Measurements campaign in EUPHORE -smog chamber in Valencia-Spain for the evaluation of the health effects of the Diesel exhausts of a newly developed Ford-made motor in cooperation with Prof. Barbara Zielneska from the Desert Research Institute (DRI) in USA in addition to the validation of the new developed NO2 Denuder. Status: Finished and published. 06.03.05-22.03.05 • DAAD funded field-project for the evaluation of the oxidation capacity during summer in Santiago de Chile including measurements all the sources and sinks of the OH radicals in the troposphere. Status: Finished and published. 23.05.05-09.06.05 • DAAD funded field-project in Santiago de Chile for the evaluation of the oxidation capacity during winter in the city, Henry law constants in dew for HONO and HCHO and the evaluation of the emission indices. Status: Finished and published. 09.07.05-23.07.05 • Participating in the HOxComp international blind intercomparison of HOX measurements techniques at the Jülich research center, Jülich, Germany. Status: Finished and publication in process. 21.08.05-05.09.05 • DBU funded field-project in Breslau-Polen in cooperation with Breslau University for the evaluation of the solvents sources in the city. Status: Finished and publication in process. 26.09.05-07.10.05 • Laboratory HONO - Aerosol measurements joint campaign at Paul-Scherer-Institute (PSI) in Villigen-Switzerland. Status: Finished and published. 09.04.07-21.04.07 • Laboratory HONO – Ice measurements joint campaign at Paul-Scherer-Institute (PSI) in Villigen-Switzerland. Status: Finished and published. 18.06.07-11.07.07 • Filed campaign for the Investigation of the oxidation capacity in the rural Area of Grignon, Paris, France. Status: Finished and publications in process.
