Multiscale Modelling for Materialsand Gene Regulation

We focus on structure-property relationships across length and energy scales, from nanoscale materials and confined liquids to soft-matter and biological regulation.

We use multiscale modelling, statistical mechanics, atomistic simulation, and AI for physics to connect microscopic structure and dynamics to design rules for electrolyte design, sodium batteries, DNA packing, enhancer-promoter contacts, and gene regulation.

Electrolyte Design for Sodium Batteries

We design liquid, solid, and composite electrolytes for sodium-metal and sodium-sulfur batteries using multiscale modelling, molecular simulation, and machine-learning-guided materials discovery.

The central question is how local coordination, interfacial chemistry, and transport pathways determine battery performance.
