Atomistic modelling · total scattering · hybrid frameworks

Thomas C. Nicholas

I am a FWO Junior Postdoctoral Fellow at Ghent University’s Center for Molecular Modelling, working on disorder, flexibility, and stimuli-induced structural change in hybrid framework materials.

I combine neutron and X-ray total scattering, atomistic modelling, reverse Monte Carlo-style refinement, and machine-learned interatomic potentials to understand how local structure gives rise to the behaviour of disordered, amorphous, and flexible materials.

Research

My work focuses on the relationship between local structural disorder and macroscopic materials behaviour. The common thread is the construction of atomistic models that are both chemically credible and experimentally constrained.

Total scattering

Using neutron and X-ray pair distribution functions to probe local and intermediate-range order in systems where crystallography is incomplete.

Machine-learned interatomic potentials

Developing and applying MLIPs to model flexible, disordered, and amorphous framework materials beyond the reach of routine first-principles sampling.

Framework disorder

Understanding how orientational disorder, lattice strain, guest loading, and amorphisation shape the behaviour of MOFs and related materials.
