Ultrafast Structural Dynamics Group
Our group develops techniques for resolving ultrafast structural dynamics in matter at timescales that are fundamental to materials science and condensed matter physics. The techniques are based on exciting matter with light and probing the response of the lattice with electrons or x-rays. We are interested in a range of phenomena and systems including phase transformations induced by strong laser excitation, phase transformations in strongly correlated systems, generation and detection of coherent lattice vibrations, and characterization of materials properties of graphene, few-layer-graphene, ultra-thin graphite & nanocrystalline diamond. Our experiments are conducted both in-house (in our Ultrafast Electron Diffraction lab) or at x-ray user facilities (Max-lab in Lund-Sweden, and ESRF in Grenoble-France). We are also interested in developing nanofluidic devices to enable in situ imaging of liquid samples using electron microscopy.
