I'm a computational engineer based in Lausanne, Switzerland with 8+ years of experience building reliable numerical software for complex computational problems. My work spans CFD, high-order methods, and scientific computing—from PDE modeling and stability analysis to porting proven algorithms into modern, safe, performant implementations. I bring the rigor of applied research to production-grade engineering, whether the target is turbulence, optimization, or trading infrastructure.

What I do

• Model & analyze: formulate and study complex dynamics (PDE/ODE, stability, transition, bifurcations, time-series structure)
• Port & harden: reimplement battle-tested numerical algorithms (Minuit2, LIBSVM, RANS) in Rust/modern Fortran with full test coverage
• Build tools: deliver open-source, reproducible, HPC-ready software (MPI/OpenMP; Rust for zero-allocation hot paths)

Focus areas

• Dynamical systems · stability/transition · bifurcations
• High-order discretizations · spectral/finite-difference/finite-element methods
• Krylov & modal decompositions (SPOD, DMD)
• Numerical optimization · parameter estimation · machine learning
• Systems programming in Rust · safe, high-performance scientific software
• Reproducible workflows (CI/CD, profiling, documentation)
