Condensed Matter Physics
Our group is studying the behavior of materials at extreme conditions (i.e. high pressure, variable temperature, high radiation fluxes) with application to condensed matter physics and chemistry. In particular we are looking at strongly correlated systems as well as materials for hydrogen storage and advanced batteries. We are also interested in developing new characterization techniques at extreme conditions.
Lasers and Accelerators
We are interested in using ultrafast laser and x-ray techniques to study dynamics in systems at extreme conditions.
Nanoscience and Quantum Engineering
Our group is looking at the effect of pressure on nanostructured materials in particular Li battery compounds.
