From February 2004, I returned to the Chair of Information Systems of the Computer Science Department of the Faculty of Mathematics and Computer Science at "Babeș-Bolyai" University.
Between October 2000 and September 2006, I was a PhD student at Dublin City University, where I investigated QoS routing using agile mobiles in MPLS networks. The actual research was done within the Switching and Systems Laboratory of the Electronic Engineering School at Dublin City University, from October 2003 to December 2003. The writing of the thesis was done in Romania (reason why it took longer than expected) from July 2004 to July 2006. My VIVA* took place on 7th September 2006, the graduation ceremony taking place on 7th November 2006.
