About me

Originally trained in Molecular Biosciences, I am since 2009 focusing on research on Environmental and Climate issues. I am currently pursuing two research directions:

CARBONACEOUS AEROSOLS:
Carbon-containing aerosols, e.g., black carbon (BC) affect the climate system and the quality of the air we breathe. However, these effects are currently associated with large uncertainties, e.g., with respect to emission sources and optical properties. In this line of research we are combining isotopic (e.g., D14C and d13C), molecular (e.g., polycyclic aromatic hydrocarbons, PAHs), and physical (e.g., light-absorption and scattering) techniques with the aim to contribute to constraining the emission sources and atmospheric processing of these components, and investigating the coupling between sources/processing and optical properties. Our approach is largely field-based, with ongoing measurements in South and East Asia, the Arctic and Africa, while chemical/isotopic analysis is conducted here at Stockholm University.

STATISTICS AND NUMERICAL ANALYSIS:
In this line of research we focus on developing/implementing statistical/numerical analysis techniques for various Environmental and Geo-applications. Much recent focus has been directed towards characterizing the uncertainties in mass-balance source apportionment calculations, mainly by using Monte Carlo techniques.
