Current Research and Scholarly InterestsMy group develops new optical and analytical tools to reveal how imperfections deep inside materials instigate the dynamics that transform them. Spanning length- and time-scales from bonds breaking at single atoms through fracture or fatigue in macroscopic materials, these defect dynamics define complex high-dimensional problems that are difficult to reconcile at intermediate scales in order to predict or understand a material's behavior. To address this challenge, my group develops new types of time-resolved experiments aimed at the elusive "mesoscale" to directly visualize how large populations of subsurface defects drive them. With these new approaches, we tackle fundamental studies of how temperature drives materials, and more applied problems that connect our new insights to structural materials, manufacturing, energy science, and beyond.
