Biography

Ladjel Bellatreche is a Professor at National Engineering School for Mechanics and Aerotechnics (ENSMA), Poitiers, where he joined as a faculty member since Sept 2010. He leads the Data and Model Engineering Team of Laboratory of Computer Science and Automatic Control for Systems (LIAS) (LIAS). Prior to that, he spent eight years as Assistant and then Associate Professor at Poitiers University, France. He was a Visiting Professor of the Québec en Outaouais, Canada, a Visiting Researcher at Department of Computer Science, Purdue University, USA and Department of Computer Science of Hong Kong University of Science and Technology, China. He is also involved in Research Postgraduate Programmes in Computer Science of several Universities and Schools in Algeria (Sidi Bel Abbès, where here he got his Engineer degree from the Department of Computer Science in 1992, National High School for Computer Science, Boumerdes University, Oran University, Béjaia University, Saida University, Béchar University, etc.).

Prof. Ladjel Bellatreche has been actively involved in the research community by serving as reviewer for technical journals (IEEE TKDE, DKE, Distributed and Parallel Database Journal, JoDS, etc.) and Editorial Board Member, International Journal of Reasoning-based Intelligent Systems, Inderscience, subject area editor of the Scalable Computing Journal, Springer and as an organizer/co-organizer of numerous international and National Conferences and Workshops (DAWAK, DASFAA, DOLAP, MEDI, WISE, EDA, JFO). Some recent conferences in which he is playing or has played major roles include DAWAK, DOLAP, MEDI, WISE Workshops. In addition, he served as a program committee member for over forty international conferences and Workshops. Ladjel Bellatreche actively contributes in promoting research in Africa and Asia, where he co-supervises several students and organizes conferences and workshops (ICT-EurAsia, MEDI, CIIA, etc.).
