I am a postdoc in the group of Jochen Blath at the TU Berlin, see also the webpage of the probability group. From October 2009 until
March 2011, I was postdoc at the IRTG SMCP based in Berlin. My PhD was supervised by Peter Mörters at the
University of Bath.
My research is in probability theory and in particular I am interested in stochastic processes in random environment (polymer models and parabolic Anderson model),
SPDEs via duality and dynamic random graph models. A more detailed description of my research can be found here.
