Petri not defending thesisPetri not defending thesisJoin us in congratulating Petri Vaattovaara for successfully defended his thesis  "The organic tandem differential mobility analyzer: Instrument development and studies of freshly nucleated and Aitken mode size atmospheric nanoparticle compositions at marine and forest environments" (yes that is a long title!) on 30 October 2009 at University of Kuopio in Finland. A large emphasis in IPY was put on fostering future Arctic scientists and since ASCOS is an IPY project it is a particular pleasure to congratulate Petri to having become the first new ASCOS PhD!
