Biography

John Murphy is an Associate Professor in Computer Science and Informatics at University College Dublin. He got a first class honours degree in electronic engineering (B.E.) in 1988 from the National University of Ireland (UCD), an M.Sc. in electrical engineering from the California Institute of Technology in 1990 and a Ph.D. in electronic engineering from Dublin City University in March 1996. He is an IBM Faculty Fellow, a Senior Member of the IEEE, a Fellow and Chartered Engineer with Engineers Ireland, and a Fellow of the Irish Computer Society. For many years he held an academic part-time position at the Jet Propulsion Laboratory in Pasadena, and acted as a consultant to the US Department of Justice. Prof. Murphy is an associate editor for both IEEE Communications Letters Journal, a member of the Editorial Board for the IET Communications (formerly IEE Proc Communications), and an associate editor for Telecommunications Systems Journal. He was the guest editor (along with Prof. Perros) for a special issue of IET Communications on Optical Burst and Packet Switching in 2009. He has published over 100 peer-reviewed journal articles or international conference full papers in performance engineering of networks and distributed systems and has been awarded over 20 competitive research grants (over 5 million euro). He has supervised 13 Ph.D. students to completion.
