PhD Position: Multiscale Modelling of Transport in Porous Electrochemical Material

This PhD research will focus on developing and applying a hierarchical, physics-informed modelling methodology to understand transport in porous electrochemical materials, linking experimentally characterized porous structures with molecular-scale and pore-scale simulations. By integrating experimental characterization with molecular-scale transport insights and morphology-resolved modelling, the research will establish quantitative morphology–transport–performance relationships and identify the pore-scale characteristics and transport mechanisms governing macroscopic performance. A computational workflow will support the systematic integration of these complementary modelling and experimental approaches across scales.

The research will focus on porous electrochemical layers, particularly porous electrodes and diaphragms typically employed in alkaline water electrolysis. In these materials, transport is governed not only by overall pore morphology and connectivity, but potentially also by physicochemical interactions within critical and highly confined pore-throat environments. Resolving how these structural and physicochemical effects influence transport across scales will provide a physically grounded basis for the development and optimization of next-generation porous electrodes and diaphragms.

PhD Supervision:

The research will be conducted primarily at VITO in close collaboration with University of Mons (UMONS), The PhD candidate will be supervised by Prof. Dr. David BELJONNE (UMONS) and co-promoted by Dr. Sai Manoj GALI (VITO).

How to Apply:

Candidates should submit their application by email to Prof. Dr. David BELJONNE (UMONS) and Dr. Sai Manoj GALI (VITO). The application package should contain a detailed curriculum vitae including relevant research experience and publications, if applicable; a motivation letter explaining the candidate’s interest in the PhD topic and relevant background; at least one recommendation letter from an academic or professional referee.

The deadline for submitting applications is 31/10/2026.

• A master’s degree in a relevant discipline such as: Chemical Engineering, Electrochemical Engineering, Materials Science or Materials Engineering, Physics, Chemistry, Computational Science or a closely related field.

• A strong motivation and interest in computational modelling of physical systems, electrochemistry, porous materials and multiscale transport phenomena.

• A strong foundation in transport phenomena, including diffusion and/or fluid flow.

• Experience with, or a strong motivation to learn, scientific programming.
