Research
Overview
My research uses molecular simulations to understand nanoscale phenomena at interfaces, with applications in thermal management, de-icing, and self-cleaning surfaces. I combine molecular dynamics with continuum methods to bridge scales from atoms to engineering devices.
Current Projects
Nanomaterial-Enhanced Cooling
High-performance electronics generate extreme heat fluxes that conventional cooling cannot handle. This project investigates how nanomaterials can enhance liquid cooling through:
- Nanoporous membranes for controlled evaporation
- Engineered solid-liquid interfaces for improved heat transfer
- Machine learning potentials for accurate molecular simulations
Ice Nucleation and De-Icing
Understanding how ice forms at the nanoscale is crucial for designing surfaces that prevent icing on aircraft, wind turbines, and infrastructure. We study:
- Heterogeneous ice nucleation on different surface chemistries
- Effects of surface vibrations on ice formation
- Design principles for icephobic surfaces
Nanoscale Heat Transfer
Heat flow across solid-liquid interfaces is governed by atomic-scale phenomena. We investigate:
- Spectral mechanisms of interfacial thermal conductance
- Effects of surface chemistry and structure
- Role of interfacial water structure
Boiling and Bubble Dynamics
Phase change at surfaces is central to many cooling technologies. Our work explores:
- Heterogeneous vapour bubble nucleation
- Effects of surface wettability on bubble growth
- Acoustically-driven nanobubble dynamics
Methods
Molecular Dynamics
We use classical MD with both empirical potentials and machine-learning interatomic potentials to simulate systems of millions of atoms over nanosecond timescales.
Multiscale Modelling
Our group develops methods to couple molecular simulations with continuum solvers, enabling simulation of macroscale problems while retaining nanoscale physics at interfaces.
High-Performance Computing
Simulations run on UK national supercomputers (ARCHER2, CIRRUS) and institutional HPC facilities.
