I am an experimentalist who studies dynamics that occur on extremely short time and distance scales. My background is in the areas of ultrafast laser, high field, accelerator, x-ray and condensed matter physics.
My research interests include ultrafast processes in the solid state and fundamental light-matter interactions. My group investigates nonequilibrium dynamics in solids with atomic level spatial and temporal resolution. Of particular interest are ultrafast dynamics including electron-phonon and phonon-phonon coupling, coherent phonon dynamics, photo-induced phase transitions, thermal transport and most recently strong-field induced attosecond electron dynamics. Our tools include ultrafast optical laser and x-ray sources (as well as ultrafast x-ray lasers such as the Linac Coherent Light Source x-ray free-electron laser at SLAC).
