MOHD SAIFUL DZULKEFLY ZAN received the bachelor’s degree in electronics, information, and communication engineering from Waseda University, Japan, in 2006, and 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 timedomain analysis (BOTDA) fibre-optic sensor. He is currently a Senior Lecturer with Universiti Kebangsaan Malaysia. His research interests involve Brillouin scattering-based fibre-optic sensors, such as BOTDA, BOTDR, optical pulse coding technique for fibre sensors, and Brillouin scattering-based fibre laser. He is also conducting research on fibre Bragg grating-based fibre sensor.
