Research

 

My research interests revolve mainly around multivariate statistical models, and, in particular, to 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, 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.
