Christos Tsiaras (Χρήστος Τσιάρας in Greek), is a member of the Communication Systems Group (CSG) since September 2011. At the same time, he joined the department of Informatics (IFI), of the University of Zurich (UZH) in Switzerland and became a Ph.D. candidate, under the supervision of Prof. Dr. Burkhard Stiller. On March 2011, he received his M.Sc. In Computer Science, with a specialization in Computer and Communication Networks, from the department of Informatics of the Athens University of Economics and Business (AUEB) in Greece. During his M.Sc. he worked with Dr. Stavros Toumpis on “Efficient Minimization of routing cost in Delay Tolerant Networks (DTNs)”. Christos holds a Degree in Physics from the University of Crete (UOC) in Greece. During his undergraduate studies he focused on the field of Computational Physics. Christos participated in 8 research projects and he has many scientific publications with high impact in top networking events since 2011. Christos domain of expertise are: Computer and communication networks, wireless and mobile communications, Internet-of-Things (IoT), wireless sensor networks, smart cities, and Quality-of-Experience (QoE) modeling.
