Associate Professor Cai Huayang received his Ph.D. degree in water resources management from Delft University of Technology in the Netherlands in 2014. During 2014-2015, he was a research fellow at the Department of Civil and Environmental Engineering, National University of Singapore. He is currently working at the School of Ocean Engineering and Technology in Sun Yat-sen University, China. His main research areas are estuarine and coastal engineering and related management issues. His current projects involve (1) the development of analytical and numerical models of river-tide dynamics in estuaries, (2) water resources management in river deltas, and (3) data-driven model for quantifying the impacts of human interventions on estuarine systems.
