Research Interests

I am interested in graphical Markov models as well as in the application of algebraic techniques in statistics (algebraic statistics). Recent projects are concerned with:

• statistical inference in complex graphical models based on chain graphs and path diagrams;
• development of graphical models for categorical data;
• study of the (algebraic) geometry of the parameter spaces of graphical models with hidden variables;
• connections between geometry of parameter spaces and properties of statistical procedures such as the likelihood ratio test;
• statistical inference in phylogenetic tree models.
