João B. Rocha-Junior is Professor at the Department of Exact Sciences at the State University of Feira de Santana (UEFS). He received his M.Sc. in Computer Science from the Federal University of Pernambuco (UFPE) in 2002. The M.Sc. was about the Architecture for Radix (a famous Brazilian search engine at that time).  In 2012, he received the Ph.D. in Computer and Information Science from the Norwegian University of Science and Technology (NTNU). The Ph.D. thesis was about the Efficient Processing of Preference queries in Spatial and Distributed Databases. Today, Rocha-Junior is Professor in the Undergraduate Course of Computer Engineering at UEFS (EComp) and permanent member of the Graduate Program in Applied Computing (PGCA) and Multi-institutional program in Computer Science (PMCC), advising Undergraduate, M.Sc. and Ph.D. students. He is also Program Chair of some conferences on Databases such as Brazilian Symposium on Databases (SBBD 2012, SBBD 2013) and International Asia-Pacific Web Conference (APWeb 2013, ApWeb 2014), and reviewer of important journals such as The VLDB Journal, Journal of Computer Science and Technology (JCST), IEEE Transactions on Knowledge and Data Engineering (TKDE), International Journal of Communication Systems IEEE Transactions on Services Computing (TSC), World Wide Web Journal (WWWJ) and GeoInformatica. He has publications in important conferences such as VLDB, EDBT and SSTD. His research interests include spatial keyword query processing, efficient processing of preference queries, distributed query processing, Spatial Databases, and Information Retrieval.
