- Built a parallel solver for magnetic equations to study turbulent liquid-metal flow in cooling blankets for nuclear fusion reactors.
- Wrote Python software to compare results of plasma turbulence models with experimental data from fusion reactors.
- Commissioned and administered 3 HPC clusters used by the Mechanical Engineering Department.
Special Scientist
University of Minnesota
- Designed and implemented an extended fictitious-domain/distributed-Lagrange multiplier method using finite elements to model flows around thin solids.
- Wrote finite element analysis code to model coupled blood flow and deformation in heart valves.
Experience
MEDESS-4MS
The system combines data provided by different European agencies in different countries with multiple oil spill models.
The network data repository (NDR) is the core of the system which harmonizes the data provided by the different providers, selects and subsets the appropriate data, transfers all data and parameters to the chosen oil spill model, triggers and runs the model, and then returns the model results for visualization.
The functionality of the NDR is exposed using REST APIs. The NDR can also be triggered automatically using satellite observations for completely automated monitoring of oil spills.
