Personal profile
Research interests
I am working in probability, more specifically on models at the intersection between discrete and continuous probability.
My research fits into three main research areas. First of all I am interested in spatial population models that are inspired by evolutionary biology and are often described in terms of stochastic partial differential equations. Here, I am trying to understand the large scale behaviour of interfaces that arise for example between different types. Secondly, I am working on stochastic processes in random environments. Currently I am working on branching processes whose behaviour is influenced by local inhomogeneities. Finally, I am interested in evolving random graphs and stochastic processes that are defined on random graphs.
