	Interessi di ricerca
	I evaluate properties formally on mathematical models using Monte Carlo simulation. My goal is to design a theory of automated algorithms for rare event simulation. I take good care to implement my ideas and test their performance in reality, on case studies as diverse as possible and largely focusing on high reliability systems e.g. described as Fault Trees. My techniques have demonstrated good performance for general stochastic models—i.e. any distribution you like—taking the same input as probabilistic model checking. I intend to extend the automated application of importance splitting to rare event analysis on hybrid systems, where currently only ad hoc approaches are applicable. Keywords: • rare event simulation • importance splitting • automation of Monte Carlo simulation techniques • formal methods in Computer Science • modelling of stochastic systems • process semantics • Stochastic Automata • GPGPUs for scientiﬁc computations • HPC.
