Salem Chakhar

Research Fellow, University of Portsmouth

Dr Salem Chakhar joined the Portsmouth Business School in August 2013 as a Research Fellow in the Operations & Systems Management subject group. He has a PhD in Computer Science from the University of Paris-Dauphine (Paris, France), an MPhil degree in Computer Science and Modelling from the High School of Management of Tunis (Tunis, Tunisia), and a degree in Computer Science from the Faculty of Economics and Management, University of Sfax (Sfax, Tunisia).

Before joining the Portsmouth Business School, Chakhar worked at the Centre for Research in Regional Planning and Development, University Laval (Québec, QC, Canada), the University of Paris-Dauphine (Paris, France), the High School of Economic and Commercial Sciences (University of Tunis, Tunisia), the Institute of Higher Commercial Studies (University of Carthage, Tunisia), and Regional Institute in Computer Sciences and Telecommunications (Tunis, Tunisia). Salem Chakhar also worked as an analyst and developer in computer science with IF and COFAT companies (Tunis, Tunisia).

His present research interests include multicriteria analysis, group decision making, decision support systems, geographical information science and systems, spatial modelling and analysis, database and information systems, web services, rough sets theory, fuzzy theory and applications, and knowledge management. Chakhar supervised 3 MSc and he is currently supervising 3 PhD and 2 MSc.
