Dr. Claudia Hak is a senior scientist in the Department for Urban Environment and Industry at NILU. She obtained her PhD in physics at the University of Karlsruhe in 2006 with a focus on the measurement of formaldehyde and other compounds involved in photooxidation processes that occur in polluted air around cities.

Claudia has been working at NILU since 2009. She is a measurement expert and leads specially designed measurement projects with a focus on the effect of emissions from industry, traffic and other pollution sources on ambient air.

Claudia is also interested in the composition of urban air and the pollution sources in cities and in this context studies advanced particle measurements (based on the composition of the particles) taken in Oslo. She has contributed to the establishment of the Urban Observatory in Oslo, which has a strong focus on particle characterization and the health effects of particles. Another area of work is within the National Reference Laboratory for Air Quality Measurements, where she guides measurement network owners with regard to the choice of reference measurement location. She is also interested in evaluating the differences between the accepted reference and equivalent measurement methods for particulate matter.
