Research:

Dr Hallquist (MH) is the Director of Gothenburg Atmospheric Science Centre. The objective of MH's current research is on atmospheric particles and their properties. The focus in MH's lab experiments is studies of aerosol formation from oxidation of organic compounds. The main research are done in connection to the G-FROST facility in Göteborg but also via experiments at large scale facilities such as the smog chambers at research centre Karlsruhe and Julich in Germany and at Paul Scherrer Institut in Switzerland. Regarding field measurement the focus is on the urban aerosol where e.g. traffic emission of particles is an important part. MH was coordinator for the urban measurement campaign Göte-2005. MH is PI for the laboratory facility G-FROST.
