Research

My primary research interests revolve around the fascinating world of multivariate statistical models, with a particular focus on graphical models. A graphical model is a multivariate statistical model that can be associated to a graph: nodes correspond to random variables and missing edges to conditional independences. I am also interested in marked point processes for event history analysis, multilevel and mixture models in non-standard situations, models for circular data, and in their connection with graphical models. I recently got involved in statistical learning, data science and models for high-dimensional data. As I love to be challenged by new topics, I have absolutely no idea on what I'm going to do in my future.
