My work mainly focuses on mixture models, robust statistics, and latent variable models, with applications in different fields such as socio-economics, environmental sciences, and psychometrics.
Specifically, my research interests are:

  • model-based clustering;
  • robust statistics;
  • ultrametric models;
  • dimensionality reduction;
  • mixed-type data;
  • model-based composite indicators.
