I am currently an Associate Professor at University of Messina and formerly an Assistant Professor at Politecnico di Milano (2011-2015). In 2001 I got the master degree in Computer Engineering from University of Catania and then, in 2006, I received the PhD degree on Computer Science and Engineering from University of Messina.
I authored and co-authored more than 130 scientific papers and contributions in international journals, conferences and books, including 2 books on peformance and dependability modeling of distributed systems. I took part to national and international projects, such as Reservoir, Vision Cloud, CloudWave (EU FP7) and SMSCOM (EU ERC Advanced Grant). I am a member of several international conference committees (NCA, NCCA, DPDNS, CBDCOM, HPCC, INCoS, DASC, ICIC, SPEDA, INMIC, UNICO, 3PGCIC, FEDICI, DySON, CSSC, WCA, DCPerf, ClIoT, IoT) and I am also involved in the editorial boards of IEEE Transactions on Dependable and Secure Computing, International Journal of Performability Engineering, Journal of Cloud Computing, International Journal of Engineering and Industries, International Journal of Big Data, International Journal of Computer Science & Information Technology Applications, International Journal of Distributed Sensor Networks. I also acted as guest editors for special issues of Journal of Risk and Reliability, Journal of Performability Engineering, ACM Performance Evaluation Review and IEEE Transactions on Dependable and Secure Computing.
My main research interests include non-Markovian modelling; performance and reliability evaluation; dependability; Quality of Service/Experience; Service Level Agreement; Parallel and Distributed Computing, Grid, Cloud, Autonomic, Volunteer, Crowd Computing; Crowdsourcing, Big Data; Software and Service Engineering; Internet of Things; Social and Urban computing, Citizen Science.
During my research activity, I contributed in the development of tools such as WebSPN, ArgoPerformance, GS3 and Stack4Things.
ACADEMIC ACTIVITIES: Since 2002, 22 courses taught and 40 students supervised.
Institutional Appointments: I) “ICT training and stage (SAT)”, scientific supervision for PoliMi Milan-Leonardo Campus; II) “Security, Safety, Defence, Disaster Management & Recovery” Cluster, PoliMi DEIB representative; III) CINI “LdA Smart Cities”, PoliMi representative, IV) “European Alliance for Innovation’, PoliMi DEIB repr.
INDEPENDENCE, AUTONOMY IN RESEARCH: Since 2008, 24 single authored papers, opening new lines of research: in 2005, a new dynamic reliability and availability modelling and evaluation approach, the Dynamic Reliability Block Diagrams; in 2008 the idea of a volunteer-based Cloud, later funded, in 2009, by the Italian MIUR as the Cloud@Home PRIN 2008 project.
INDUSTRIAL RESEARCH CENTER COLLABORATIONS: Collaborations through research projects (IBM, Telefonica, CISCO, Thales, Oracle, Elsag Datamat, ST, GE, Engineering, Telecom, Hyperborea, etc.). Others have been activated as stages and master theses at: SAP Belfast, ST, Deloitte, Ericsson, Bosch, ATM, Emaze, Brain Force, etc.
