Mohamad Kamarol Mohd Jamil received his B.Eng (Hons) in Electrical Engineering from Universiti Technology Mara, Malaysia (UiTM), in 2000. He joined Universiti Sains Malaysia (USM) with a University ASTS Fellowship in 2002. He received the M.Eng. degree from Kyushu Institute of Technology, Japan in March 2005. In April 2005 he started his doctor course research study, which concerning the study on partial discharge properties in vacuum interrupter for the fundamental study of diagnostic technique development and the analysis of the insulation properties of CF3I gas as a potential candidates for the substitution of SF6 gas. He received his D.Eng. in March 2008. Within his doctor course study, he has received a Chatterton Young Investigator Award from the IEEE International Symposia on Discharges and Electrical Insulation in Vacuum (ISDEIV) in 2006. Prior to joining the university, he worked as a senior engineer at Sankyo Seiki (M) Sdn. Bhd. for almost 8 years. He was a Visiting Researcher at the High Voltage Lab at Kyushu Institute of Technology, Japan from 2013 to 2014. He was a senior lecturer at USM, Malaysia since 2008 and has been promoted to Associate Professor at the same university in Dec 2014. His research interest includes the insulation properties in oil palm and solid dielectric material, insulation properties of environmentally benign gas, PD detection technique for insulation diagnosis of power apparatus and electrical machine. He is also involved in temperature rise and short circuit electromagnetic study of busbar system, and HVDC. Dr. Mohamad Kamarol is a Professional Engineer, Chartered Engineer and a member of IEEE, IET, Board of Engineering Malaysia (BEM) and Institute Engineering Malaysia (IEM).
