Ricerca

Monica Chiogna tries to contribute, along with her research group, to the development, application and dissemination of biostatistics. The group closely interacts with biomedical researchers and epidemiologists and tries to produce statistical solutions that represent at best known mechanisms of the systems to be understood or predicted. A description of the main research interests of the group can be found here.
