Marvin Sirbu received B.S. degrees in Electrical Engineering (1966) and Mathematics (1967), an M.S. degree in Electrical Engineering (1968) and an Sc.D. in Electrical Engineering with a minor in Economics (1973) all from the Massachusetts Institute of Technology.  Dr. Sirbu remained at MIT as a Research Associate in the Center for Policy Alternatives before joining the faculty of MIT's Sloan School of Management.  While at MIT he directed its Research Program in Communications Policy.  

In 1985 he moved to Carnegie Mellon University with a joint appointment in Engineering and Public Policy, the Tepper School of Business, and Electrical and Computer Engineering.  In 1989 He founded CMU's Information Networking Institute which engages in  interdisciplinary research and education at the intersection of telecommunications, computing, business and policy studies.

Dr. Sirbu spent the 2006-2007 academic year at the Ecole Nationale Supérieure de Télécommunications (now Télécom ParisTech)
