Profilo didattico-scientifico

Biografia

Michele Savi si è laureato in Ingegneria delle Telecomunicazioni presso l'Università di Bologna nel marzo 2004.

Ha conseguito il dottorato di ricerca in ingegneria elettronica, informatica e telecomunicazioni presso il dipartimento di elettronica, informatica e sistemesitica (DEIS) - Università di Bologna

Dal maggio a dicembre 2008 ha svolto un periodo di ricerca all'estero di sei mesi presso il 'Department of Computing and Electronic Systems' dell'University of Essex, Colchester (UK)

Attività didattica

Attività di laboratorio per il corso "Sistemi di commutazione" tenuto dalla Prtof. Carla Raffaelli presso l'università di Bologna, facoltà di Ingegneria, negli anni accademici 2006-2007, 2007-2008 e 2008-2009. Durante le lezioni di laboratorio ha supportato gli studenti per:

Ha svolto negli anni accademici 2006-2007, 2007-2008, 2008-2009 e svolge tuttora attività di tutorato per il corso di "reti di telecomunicazioni LA" tenuto dal Prof. Giorgio Corazza presso l'università di Bologna, facoltà di Ingegneria. In particolare supporta il Prof. Giorgio Corazza durante gli esami in laboratorio.

E' stato coinvolto come relatore nella Master School "Photonics in Switching" del progetto Europeo BONE "Building The Future Optical Network in Europe", tenutasi a Budapest (Ungheria), dall'8 al 10 settembre 2010. Michele Savi ha presentato tre diverse lezioni di un'ora e mezza ciascuna, focalizzate su architetture di commutazione ottica, risoluzione della contensa e valutazione delle prestazioni. Le tre lezioni erano intitolate:

Attività scientifica

Svolge attivita' di ricerca nell'ambito di architetture di commutazione ad alte prestazioni per le reti ottiche a commutazione di pacchetto (OPS) e di burst (OBS), schemi di risoluzione della contesa nei diversi domini e algoritmi di controllo per la gestione dell'inoltro dell'informazione, architetture elettro-ottiche, architetture multigranulari.

È coinvolto nei progetti europei per le reti di eccellenza IST e-Photon/ONe+ e BONE. Collabora in progetti di ricerca italiani PRIN finanziati dal Ministero dell'Istruzione dell'Università e della Ricerca riguardanti le reti ottiche.

Ha svolto e svolge regolarmente attività di revisione per le riviste IEEE Journal of Lightwave Technology, IEEE Optical Switching and Networking, IEEE Elsevier Computer Networks, IEEE Transactions on Communications e per le conferenze internazionali ICC, Globecom, Infocom, Opticomm, ONDM, QoS-IP, Broadnets.
