Dr. Hussein is a Research Professor at the Gas Processing Center at Qatar University and affiliated with the Chemical Engineering Department. Dr. Hussein obtained his PhD from the Chemical and Materials Engineering Department at University of Alberta, Canada in 1999. His PhD Thesis won the Canadian Society of Rheology Graduate Student Award for the year 1999. Through his academic life, Dr. Hussein received many Awards, Scholarships and Prizes at University of Khartoum, Sudan; University of Alberta, Canada; KFUPM, Saudi Arabia and Qatar University. He supervised more than 60 MS/PhD students and postdoctoral fellows. Dr. Hussein is actively involved in research in the area of polymers and materials and has published more 200-refereed journal articles and more than 30 US patents. His research addresses the challenges of oil and gas production with focus on oilfield chemistry, polymers and complex fluids in petroleum engineering applications. His specific interests include: scale removal from oil and gas wells using green formulation, polymeric gels for loss circulation and water control, Enhanced Oil and Gas Recovery (EOR/EGR), development of new materials for oil-water emulsification, and drilling Fluids. He uses different experimental techniques in addition to molecular simulations and computational fluid dynamics.
