Experienced Postdoctoral researcher with a demonstrated history of working in the higher education industry. Skilled in computational methods, modeling and simulation in mechanical engineering with particular emphasis on thermal energy and its relevant applications. PhD graduated from the University of Aveiro, 2016; the PhD research focused on Concentrated Solar Power systems and its and its contribution to meeting energy demand and reduce the environmental damages. The study was innovative and the main novelty is the environmental and economic investigation using Life Cycle Assessment having as objective function the thermodynamic property exergy. After completing the PhD degree, two article journals were published; joined the Department of Mechanical Engineering, Sabratha University, Libya in September 2016 as Invited assistant researcher; and since June 2017, postdoctoral fellowship at the University of Aveiro, Department of Mechanical Engineering & Bosch Thermotechnology center Aveiro. 1998 to 2008, Engineer, Research and Manufacturing Center, Tripoli. 2008-2012, lecturer, University of Az-Zawiya, Mechanical Engineering Department.
