About

CV

Widar Weizhi Wang is a senior researcher at the Department of Civil and Environmental Engineering at the Norwegian University of Science and Technology. His research focuses on numerical modelling and model development for marine hydrodynamics in ocean engineering, coastal engineering and environmental engineering. He has been actively involved in the numerical model coupling, metocean down-scaling procedure NORA-SARAH and the groundbreaking new hydrodynamic model REEF3D::NFLOW.

He obtained his PhD degree from the Norwegian University of Science and Technology with the thesis titled 'Large-scale phase-resolved wave modelling for the Norwegian coast'. During his PhD, he explored different wave models for the E39 coastal highway ferry-free fjord-crossing project and participated in the development of two numerical wave models: the quadratic non-hydrostatic shallow water model REEF3D::SFLOW and the fully non-linear potential flow model REEF3D::FNPF in the open-source hydrodynamic framework REEF3D. Before his PhD, he received master’s degree in Naval Architecture and Ocean Engineering from Chalmers University of Technology in Sweden.
