Short Bio:

Prof. Leobino N. Sampaio is associate Professor in the Computer Science Department at Federal University of Bahia (UFBA). He holds Bachelors (1996) and M.Sc. (2002) degrees in Computer Science, both received from Salvador University (UNIFACS) and Ph.D. in Computer Science From Federal University of Pernambuco (UFPE) in 2011. He has a large experience in computer networks, in particular, network measurements and performance evaluation. Currently, Dr. Sampaio is researcher and leader of the Group of Algorithms and Distributed Computing (GAUDI) and infrastructure and Systems for Networks and Telecom (INSERT). Dr. Sampaio is member and assistant coordinator of the RNP’s Technical Committee on Network Monitoring (CT-Mon), member of the Brazilian Computer Society (SBC), and member of the Steering Committee of the Network of Experimentation in the Future of the Internet between Brazil and Europe (FIBRE). Dr. Sampaio is reviewer of international journals, such as IEEE Communication Magazine, Computer Networks (1999), the IEEE eTransactions on Network and Service Management, IEEE Wireless Communications Magazine, and the IEEE Transactions on Network and Service Management. His research interests include Information-Centric Networking (ICN), in particular the NDN Architecture, applied to mobile scenarios, such as VANETs, FANETs, and IoT. He is also interested in Future Internet Architectures, such as Software-Defined Networking (SDN) and new network paradigms and solutions, e.g., Tactful Networking and Blockchains.
