Research Summary

At present holding a junior research position in environmental oriented atmospheric science. The objective of this position is to further developing the existing research concerning atmospheric processes related to environmental science. In particular development of measurement techniques and methods for determination of physical or chemical parameters related to atmospheric science. The background as chemist and present position at the department of physics will facilitate the tasks in this cross-disciplinary research field.

Research Projects

• The impact of atmospheric oxidation processes on physical and chemical properties of aerosol particles. Project supported by The Swedish Research Council.
• Göte-2001. Measurement of gas and particulate air pollutants adjacent to a main approach road to Göteborg, RV45, in the suburban of Surte. The objectives are to:
• Quantify the contribution from road traffic to the fraction of ultra-fine particles
• Exposure to PM_2,5. Exponering för PM_2.5 vid vedeldning i småhus, en jämförelse mellan vedeldares och kontrollers dygnsexponering. A joint project with Occupational and Environmental Medicine at Sahlgrenska University Hospital.
