About me
Currently, lab tech with focus on biogeochemistry analytical systems in ACES-b.
Main responsibilities include:
- Maintenance and troubleshooting of the unit’s core-biogeochemistry analytical systems (including TOC analyzer, UV-VIS/Fluorescence instrument, Ion Chromatograph, Nutrient analyzer, GC-FID, GC-FID-ECD and GC-CVAFS/CVAFS for Hg analysis and Hg, pH-electrodes, surface area analyzer) and freezers.
- Quality assurance and continuity of e.g. the analytical methods associated with the techniques mentioned above. This includes bridging between generations of PhD students and post docs.
- Maintaining inventories of samples and standards.
- Contribute to the laboratory safety work at the unit by providing support in laboratory and field risk assessments, purchasing of chemicals, handling of gases and chemical inventories to the research groups, as well as assist the head of the unit in documentation and follow-up of the laboratory safety work.
- Management of some of the laboratories at the unit.
Taught in the following courses;
- Atmosphere, Biogeosphere and Climate Change-ABCC
- Large Scale Challenges to the Climate and Environment-LSCCE
- Laboratory Methods in Envirnomental Science
- Fieldwork course for undergraduates
My previous research work was on characterization of the carbonaceous aerosols in SSA in the light of their sources, properties and role in climate change/air pollution.
