Biografi
My specific field of research is random graphs, especially random trees. I defended my PhD thesis “Split Trees, Cuttings and Explosions” in Uppsala in February, 2010 with Prof. Svante Janson as primary supervisor. Thereafter I spent two years abroad on a postdoc fellowship from the Swedish Research Council (VR), the first 8 months at INRIA in Paris with Prof. Philippe Flajolet and Dr Nicolas Broutin and then for 1½ years at Univ of Cambridge with Prof. Béla Bollobás and his group. In August, 2012 I got a tenured position as Assoc. Prof. (Senior Lecturer) at the Department of Mathematics at Stockholm University and from October, 2014 I am a Docent (associate professor) in Mathematics. From August 2015 I am working as docent in mathematics (probability theory and analysis) at the Dept of Mathematics at Uppsala University. In January 2018 I received a Ragnar Söderberg Fellowship based on my score A (highest) evaluation of my project application to the European Research Council with funding for 5 years matching an ERC fellowship.
