I am currently full professor at the Department of Computer Engineering, Systems and Industrial Engineering, University of Roma "Tor Vergata", Italy. My general research interests are in the field of methods and tools for the validation of extra-functional quality indices (in particular, performance and dependability indices) for computing and communication systems.
Within this general framework, I have recently focused my research activity on mobile computing systems and on geographically distributed service-oriented systems. For such systems, I am pursuing two highly correlated research lines:
• definition of methodologies for the design and analysis of adaptable applications;
• definition of tools to automate the generation of analysis models for extra functional quality indices (like performance, reliability, ...), with particular reference to the applications and systems considered in the former research line.
In the past, I have been interested in the definition of methodologies for the performance and dependability analysis of fault-tolerant systems (in particular, "performability" indices), and for the performance analysis of wireless communication protocols.
