Through my inter-disciplinary research I seek to understand the water and sediment flow at the interface between land and ocean and their impacts on coastal protection and natural hazards mitigation through CFD modeling and data analysis.
The core approaches in my research are: (1) Developing numerical model to simulate the important hydrodynamic and morphodynamic processes in the coastal zone, and (2) Analyzing big data generated by various in-situ and remote-sensed measurements of tides, waves, storm surge and hurricane morphological changes.
My research has a broad range of applications including coastal structure design, coastal restoration (for example, the state-wise restoration and protection master plan in Louisiana, http://coastal.la.gov/our-plan/2017-coastal-master-plan/). Currently, I am working with scientists at JPL/Caltech towards NASA's satellite mission to make the first global survey of Earth's surface water.
The following are some of my projects on CFD simulation, and more projects on machine learning are available in the next page.

-- Water Wave Mechanics
Particle Tracking & Tracer StudyWe developed a toolbox to simulate the fate of oil slick after oil spill in the Gulf of Mexico. The oil particle was moving under the combined effects of wind, wave and currents.
This toolbox was developed in HPC framework and highly efficient for large number of particles. On the right it is the simulated oil parcels from BP Deepwater Horizon oil spill under a hypothesized hurricane hitting the Louisiana coast. |

--Sediment Transport and Coastal Morphology
Sediment Transport & MorphodynamicsThe objective of this project to provide different designs to protect the beach from erosion and evaluate the effectiveness through numerical simulations.
This figure is a numerical simulation for the morphological change of a sandy beach (protected by breakwaters) during a flooding event caused by storms. The right panels are the cross-section views of the beach profile. |

Developed a coupled modeling system to study the hurricane-induced sedimentation on coastal wetlands.
The animation show the sediment flux between the continental shelf and two coastal estuaries (Barataria Bay and Terrebonne Bay) in the Louisiana coast during Hurricane Gustav. |
