I am interested in using the ROMS to study the dynamic process in the tropical ocean, polar ocean and coastal ocean. I have investigated the relationship between sea surface salinity anomalies, equatorial undercurrent anomalies and the Indian Ocean Dipole. Within the framework of COAWST, I have coupled ROMS with CICE and configured this model in the Arctic Ocean. I also explored the wave-ice interactions with ROMS-Budgell model by including the wave-induced mixing and sea ice break-up. At UNSW, I focus on the eddy-mean flow interactions in the East Australian Current system.
