Mohd Saiful Dzulkefly Bin Zan received the bachelor’s degree in electronics, information, and communication engineering from Waseda University, Japan, in 2006, the master’s and Ph.D. degrees from the Shibaura Institute of Technology, Japan, in 2011 and 2014, respectively. During his Ph.D. study, he proposed the optical pulse coding technique to improve the sensing performance of Brillouin optical time-domain analysis (BOTDA) fiber-optic sensor. He is currently a Lecturer with Universiti Kebangsaan Malaysia. His research interests involve Brillouin scattering-based fiber-optic sensor, such as BOTDA, BOTDR, optical pulse coding technique for fiber sensors, and Brillouin scattering-based fiber laser. He is also conducting research on fiber Bragg grating sensor.
