  • Non-Fourier Heat Transfer (in nanomaterials and from nano heat sources such as transistors)
  • Ultrafast measurement of heat transfer using optical and x-ray spectroscopy (femto-to-nanosecond time scale)
  • Ultrafast evolution of structural/magnetic/electrical phase transitions in ferroelectrics, multiferroics, thermoelectric, battery materials (superionic conductors), photovoltaics, and quantum materials (femto-to-nanosecond time scale)
  • Thermal transport and phase transition of nuclear materials
  • Thermodynamics of phase transitions
  • Irradiation damage evolution
  • Direct probing of atoms, electrons, electron spins and their dynamics using neutrons, x-rays, and optical spectroscopy
