About Me

I am a Visiting Assistant Professor in the Department of Computer Science at The College of Charleston. I received my doctorate in Computer Science at the University of North Carolina at Charlotte under the supervision of Professor Zbigniew W. Ras in the field of data mining; more precisely, object-driven and temporal-based action rules.

I earned my Bachelor of Science in Computer Information Systems from Yarmouk University, Irbid, Jordan, and my Master of Science in Computer Science from Northern Illinois University, IL.

Other than data mining and machine learning, my interests lie in computer vision, intelligent tutoring systems, crowdsourcing and collective intelligence, gamification, social networks and smart web/mobile systems and their uses to connect people and promote societies. I am also interested in philosophy, and few topics in social science; such as cognitive psychology, evolutionary psychology, social epidemiology, and anthropology.
