About
PhD CFD Engineer and Postdoc with 5+ years of combined academic and industry experience delivering end-to-end simulation support — from 3D modeling and mesh generation to RANS, LES, and LBM execution on CPU/GPU high-performance computing (HPC) architectures.
Strong expertise in turbulence modeling, external aerodynamics, flow optimization, aeroacoustics, and experimental wind-tunnel validation. Proficient in developing Python-driven workflows to automate large-scale data post-processing and streamline simulation pipelines.
Experienced with multiple commercial and in-house solvers: OpenFOAM, Ansys Fluent, and Altair (AcuSolve & UltraFluidX). Proven track record of publishing Q1 journal research, coaching others in advanced CFD methodologies, and delivering results under real-world engineering constraints.
Key achievements:
- Validated LBM CFD predictions against wind-tunnel data with excellent pressure-coefficient agreement (Q1 journal)
- Benchmarked GPU/LBM vs. CPU/LES, demonstrating superior computational efficiency on HPC supercomputers
- Optimized marine ballast-water-treatment pipelines using RANS simulations (Q1 journal)
- Conducted aeroacoustic research on bio-inspired wings at the University of Southampton (accepted in Springer's Advances in Aerodynamics Q1 journal)
- Achieved highest score on Aerodynamics assessment at MIA School of Race Engineering, Silverstone
