We are congratulating our colleague Ibtissem Ben Makhlouf on receiving her doctor's degree at our department! The examination took place at the January 26 2016 and the topic was Comparative Evaluation and Improvement of Computational Approaches to Reachability Analysis of Linear Hybrid Systems. This time the usual procession to the town hall had an easy way back since our handicapped colleague Dzenan Dzafic helped energetically.
