My research interests include physical oceanography in coastal oceans and novel data analysis methods in meteorology and oceanography. My current work is focused on West Florida Shelf, aiming to understand its ocean circulation dynamics and processes of air-sea interactions. Past research activities include observational studies of ocean circulation in the Asian marginal seas (East China Sea, South China Sea, NW Pacific east of Ryukyu & Taiwan Islands) and numerical modeling of coastal ocean circulation in the NE Pacific (Columbia River plume).

Research highlights:
- Satellite-tracked surface drifters in the Gulf of Mexico
- Modeling the Deepwater Horizon oil spill trajectory with hindcast/forecast numerical ocean circulation models and satellite imagery
- Seasonal variation of the currents on the West Florida Shelf observed with long-term moorings
- Mean circulation on the West Florida Shelf observed with long-term moorings
- Performance of CODAR SeaSonde in mapping surface ocean currents on a low energy shelf
- Numerical modeling of the Columbia River estuary-plume-shelf circulation
- Rectification of the bias in the wavelet power spectrum
- Evaluation & applications of the Self-Organizing Map in oceanographic data analysis
- Coastal ocean dynamics - sea surface height estimated across the West Florida Shelf
- Coastal ocean dynamics - momentum balance on the West Florida Shelf

Animations of oceanographic observations on the West Florida Shelf:
- Surface currents measured with WERA (Wellen Radar) High-Frequency Radar system
- Surface currents mapped with CODAR High-Frequency radar system (radial and total velocity maps, 2003~2008 )
- Moored ADCP ocean current observations (Monthly movie show, 1998~2005)
- EcoHAB hydrographic transects (1998~2001 animations)
