Prof. Fayçal Kharfi is Professor of Physics at the Department of Physics of Ferhat Abbas-Setif1 University. He teaches several courses on molecular imaging, computed tomography, radiation physics and application, and medical physics. He is also the actual Director of the Dosing, Analysis, and Characterisation with high resolution Laboratory (LDAC). The focus of his actual research activities is on ionizing radiation application. His research crosscuts a range of areas in radiation dosimetry, radiation therapy, computed tomography, archaeological dating, and nuclear medicine. His overarching goals are to understand how ionizing radiations act on matter and how they could effectively be applied for many purposes and applications such as therapy, archaeological dating and imaging. He is an associated editor of the “Technology in Cancer Research & Treatment” SAGE journal. He published many research and educational works in various international journals, books, and conference proceedings. He is frequent reviewer, expert in radiation application, and member of many international associations such as the international society of neutron radiography (ISNR) and the international association on engineers (IAENG). He supervised many doctorate thesis and research projects in the fields of radiation dosimetry and application, radiation therapy, and medical imaging.  He contributes to the organisation of numerous national and international conferences and workshops on medical physics and radiation application.
