My scientific interests mainly focus on basic research on aerosols and their effects on the earth's climate, as well as air quality, health and sustainability. The most modern instrumental evolution in the field of nano-analytics open up versatile possibilities to develop new concepts and methods for the investigation and detailed characterization of aerosol formation processes. My main research interest includes the chemical oxidation processes of volatile organic compounds in the atmosphere leading to new-particle formation (NPF) and secondary organic aerosol (SOA). Based on the knowledge of various non-volatile substances, there is strong interest in further research in the field of inorganic and organic aerosol particles and ultrafine dusts and their effects on our health and environment. The main research focus is based on the online detection including the elementary and physical characterization of nucleating clusters and their gaseous precursors by help of modern mass spectrometry techniques in laboratory studies, as well as at CLOUD experiments at CERN, Geneva. These oxidation flow reactor experiments aim for a better understanding in atmospheric gas-phase reactions, chemical functionalities and their interactions to the microphysics in formation of nucleation nuclei and growth of aerosols. Another central aspect of my research pursues a detailed description of chemical reactions in the bulk- and particle-phase of SOA and the associated aging reactions of atmospheric gases and particular matter. The aforementioned interests are intended to be primarily achieved by in-situ and offline experiments and studies including a PAM oxidation flow reactor and atmospheric samples from different environmental sides. The gas-phase and ultra-fine particle samples are analyzed using atmospheric pressure chemical ionization (APCI), as well as high performance liquid chromatography (HPLC) characterization coupled to ultrahigh-resolution orbitrap mass spectrometry (UHR-Orbitrap-MS). With the help of a better description of the various chemical conversion processes from volatile emissions into atmospheric aerosols, our understanding of fine dust in our environment and its climatic and health interactions can be improved.
