• Role: Senior Researcher and Part-time Professor

Research Interests revolve around multiphase flows, electrochemical processes, and sustainable energy systems. Key topics include Marangoni effects, gas distribution in electrolyzers, hydrogen bubble dynamics, and ohmic resistance optimization. His work addresses challenges in scaling up electrolysis technology for industrial applications.

Recent Publications highlight numerical simulations of bubble growth, X-ray imaging of gas void fractions, and experimental validation of Marangoni forces in both acidic and alkaline electrolytes. These studies inform innovations in membrane design, electrolyzer architecture, and cost-effective hydrogen production.

Collaborations include Nobian, NWO-funded projects (ECCM KICKstart DE-NL program), and partnerships with institutions like Helmholtz-Zentrum Dresden-Rossendorf (HZDR). Funding sources include the Top Sector Energy Subsidy from the Dutch Ministry of Economic Affairs.

Technical Contributions involve developing sharp interface methods for Navier-Stokes simulations, modeling tertiary current distribution, and optimizing zero-gap electrolyzer designs to reduce hydrogen leakage while maintaining flexibility.
