I'm a computational engineer based in Lausanne, Switzerland with over 10 years of experience delivering simulation-driven solutions for complex physical systems. My work spans CFD, high-order numerical methods, and high-performance computing—from PDE modeling and stability analysis to scalable workflows and reproducible post-processing. I bring the rigor of applied research to production-grade engineering, with a focus on turning physics into reliable, validated software.

What I do

• Model & analyze: formulate and study complex dynamics (PDE/ODE, stability, transition, bifurcations, time-series structure)
• Design studies: build defensible experiments with validation, verification, and uncertainty considerations
• Build tools: deliver open-source, reproducible, HPC-ready software (MPI/OpenMP; CPU/GPU-friendly workflows)

Focus areas

• Dynamical systems · stability/transition · bifurcations
• High-order discretizations · spectral/finite-difference methods
• Krylov & modal decompositions (SPOD, DMD)
• Reproducible HPC workflows (profiling, CI/CD, documentation)
• CFD roots; methods generalized beyond fluid mechanics
