About Grégory

Optimize the thermal performance of your systems.

With 14 years of experience in thermal management and CFD simulations for electronics, I can help you improve the reliability, reduce costs, and enhance the efficiency of your thermal systems.

I can assist you with:
✅ Design and optimization of electronic cooling systems (heatsinks, TIMs, liquid/air cooling for PCBs, power, batteries)
✅ Advanced thermal simulations (steady-state, transient, multiphase): identification of hot spots, design validation
✅ Optimization of HVAC & air conditioning infrastructures for data centers, server rooms, and industrial environments
✅ Thermal analysis of racks, airflow in data centers
✅ Design or improvement of cooling systems: air, liquid (immersion, direct-to-chip), or hybrid
✅ Support for prototyping and model/experiment correlation with your teams

I am available for one-off audits, targeted simulations, or long-term support.
