Teaching assistant for the academic course on “Telecommunications Networks” at the School of Engineering of the University of Bologna for the academic years 2006-2007, 2007-2008 and 2008-2009. Michele Savi supported professor Giorgio Corazza during the exams in the Laboratory.

Involved as lecturer in the Master School "Photonics in Switching" of the European Project BONE "Building The Future Optical Network in Europe", hosted in Budapest (Hungary), 8-10 September 2010. Michele Savi presented three lectures (1 hour and 30 minutes each), focused on optical switching architectures, contention resolution in wavelength (and time) domain and performance evaluation tools. The three lectures were:

Research

His current research interests are in the fields of high-performance optical switching node architectures for optical packet switched (OPS) and optical burst switched (OBS) DWDM networks, contention resolution schemes and related scheduling algorthms, hybrid electro-optics architectures, multi-granular architectures.

He is involved in the IST e-Photon/ONe+ and BONE Networks of Excellence European projects. He also collaborates to Italian research projects on optical networks.

He served as referee for 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.
