My key expertise is within assessment of human exposure to air pollution and assessment of atmospheric nutrient loadings on nature, applying integrated monitoring assessment (combined use of measurements and model calculations); this was the topic of my higher doctoral degree. I am working with personal exposure monitoring (PEM) and I am deeply involved in testing and applying low-cost sensors and passive samplers for PEM. I am a modeler by training and have played a key role in the development of the Operational Street Pollution Model (OSPM); a model that is now applied in more than 20 countries around the world. I took part in the development of the Eulerian Backward Ierative (EBI) method for solving chemistry in chemistry-transport models (CTMs) used by the US-EPA as their standard method. In my PhD project I developed a Lagrangian chemistry-transport model for studying atmospheric degradation of biogenic Sulphur compounds in the atmosphere. Parts of this model were later used for developing a model for atmospheric deposition to nature (ACDEP – atmospheric chemistry and deposition model) that for 10 years was applied for mapping Nitrogen and Sulphur deposition to Danish nature.
