Dr NAK Nandasena

BSc (Eng.), M.Eng., PhD


I completed my Masters and Ph.D. in Hydraulic and Coastal Engineering at Saitama University, Japan. Before Joining the University of Auckland, I worked as a postdoctoral research fellow for two years with funding from the Japan Society for the Promotion of Science.
