Mesoscale Materials Modeling Laboratory

The Mesoscale Materials Modeling Laboratory focuses on modeling the materials microstructures and evolutions and understanding their relations to materials properties based on mesoscale computational methods (such as phase-field modeling). We aim to understand experimental observation and provide guidance to materials design and optimization. Current topics include:

  • Thermal, electrical, chemical, mechanical coupling behaviors and in nanoscale functional oxides
  • Charge transport phenomena in energy materials
  • Ferroelectric switching under electrical and mechanical excitations
