Prof. Patrizia Catellani, an expert in social psychology and advanced statistical modeling at the Catholic University of the Sacred Heart – Milan, will help to identify the socio-economic causes and consequences of loneliness using probabilistic models optimized by machine learning techniques. She will also lead the development of a decision support system to support the development of interventions against loneliness in different EU contexts. She will pay particular attention to diagrams and models that can be easily interrogated by relevant stakeholders, such as policy makers and practitioners
