1997 Ph.D. in Physical Chemistry, University of Sheffield, Department of Chemistry:
• Monte Carlo simulation study of hard-sphere chain polymers
• Advisors: Prof. George Jackson and Prof. Tom McLeish
• Investigation of the shape statistics of tangent-hard-sphere polymer chains using Monte Carlo (atomistic) simulations


thermodynamics in relation to energy and the environment

  • CO2 phase behaviour: in mixtures with reservoir fluids (e.g., enhanced-oil recovery); in aqueous systems; in mixtures with electrolytes (e.g., for sequestration in saline aquifers)
  • organic Rankine cycles, and related devices for the conversion of waste heat to useful energy

Statistical thermodynamics and phase equilibria

  • molecular-based equations of state, e.g., SAFT, and their development
  • industrial gas-polymer systems
  • liquid-crystal systems
  • intermolecular potentials and their influence on mixtures and phase equilibria

Flow assurance

  • thermodynamic modelling of gas hydrates for application in reservoir / flow simulations
  • thermodynamic modelling of crude-oil systems, with particular emphasis on asphaltenes and asphaltene precipitation


  • atomistic (molecular dynamics (MD) and Monte Carlo (MC)) and mesoscale (coarse-grained MD and kinetic-MC / finite-element) simulations
  • adsorption of fluids on solid surfaces
  • multiscale and hierarchical simulations
