In 2010 I received my PhD (Chemical Physics,supervised by Wolf Geppert) at Stockholm University after having experimentally studied dissociative recombination reactions of relevance for the chemistry in planetary ionospheres and interstellar clouds. Then I did a two-year postdoc at the Department of Physics at Imperial College London together with Marina Galand, where I by numerical means investigated the ionospheric particle balance of Titan (the largest satellite of Saturn) using Cassini data. I developed also a pure gas-phase model to investigate the ionospheric particle balance in the coma of comet 67P/Churyumov-Gerasimenko, the target comet for the ESA Rosetta mission. During my postdoc at the Swedish Institute of Space Physics in Uppsala I am continuing working on Titan's ionosphere, but focus in particular on extending the cometary model to also take into account gas-dust interactions.
