Research Interests

I lead a research group that studies topics ranging from thawing Arctic permafrost carbon-climate couplings, to sources and radiative effects of aerosols in the Brown Clouds over South and East Asia, to the degradation of organic contaminants at industrial sites.  
Our work is based on field observations and sampling, often using own-developed techniques, in remote locations such a  on ships in the Arctic and  on atmospheric observatories in both remote receptor locations (Tiksi, NE Siberia; Hanimaadhoo Island, the Maldives and Jeju Island, S. Korea) and in megacity locations in India and China.  We emphasize molecular, isotopic and even molecular-isotopic probing of the organic matter to improve our understanding of its source, degradation status and properties.
We have currently organized ourselves in three research tracks: Aerosols, Arctic-C and Molecular and Isotopic Analysis (MIA).
I will try to not wait another ten years to update my homepage…In the meantime, email me or anyone else in the group (links to the right) if you have any questions!
