Capabilities

Carry out atomistic-based simulations to compute properties of materials (Monte Carlo, molecular dynamics, coarse-grained)

  • Phase equilibria (VLE, LLE, SLE, etc.)
  • Thermodynamic properties (heat capacity, density, expansivity, etc.)
  • Transport properties (viscosity, conductivity, diffusivity, mass transfer)
  • Insight (fluid structure, explain behavior, etc.)

Develop new simulation methods

  • Melting points
  • Advanced free energy calculations
  • Nonequilibrium molecular dynamics

Develop predictive force fields using ab initio simulations
Systems of interest

  • Liquids, crystalline materials, nanoporous materials
