Short presentation
Dynamic non-equilibrium processes in crystalline materials govern the performance of devices and the formation of new materials. These processes take place at the sub-nanometer scale such as the arrangement, movement and relaxation of atoms, to the macroscopic scale where inter-particle interactions drive device performance.
My research focuses on using diffraction techniques to follow these non-equilibrium changes and direct the design of new materials.
