We study the phonons and their interactions with other exciations (electron, spin, magnon, other phonons) and nanostructures in materials.

We use neutron and synchrotron scattering (both elastic and inelastic) at national facilites to understand materials. We also do Raman spectroscopy.

We use high pressure technique based on diamond anvil cells to understand the dynamics and structure of materials, especially interfacial phenomenons.

We use first-principles methods to simulation materials. We also do instrument simulation for the scattering experiments.
