4 Work Activity
Research activity develops in the field of statistical modelling of survival data from both an applied
and a theoretical view point.
The applied activity concerns the statistical analysis of clinical trials and observational studies in
biomedical research.
The theoretical research aims at deriving novel methodologies for modelling life-time data. Scientific
activity has been centered on assessing the goodness of fit of survival models via residual analysis,
estimating time dependent effects in the Cox model, describing complex data through mixture models.
The potentialities of the Bayesian approach have also been explored with the purpose of developing
predictive models.
