RESEARCH INTERESTS

I'm currently working on stochastic (partial) differential equations (S(P)DEs) and am particularly interested in processes driven by random martingale measures. My most recent project focused on establishing analytical properties for conditional densities of partially observed jump diffusion processes.

​

I also recently got interested in rough path theory and the fascinating new tools it provides. In a current project we try to use these to obtain an approximation for the prediction density, associated to the conditional expectation of a future state.

​

Apart from probability and stochastics I'm also interested in estimation for (nonlinear) infinite-dimensional systems. In my Master's project we derived an observer for a class of semilinear infinite-dimensional systems, based on the extended Kalman filter.
