Research in The Flannigan Lab is highly interdisciplinary and includes aspects of materials science, physical chemistry, and solid-state physics for the study of structural, electronic, and magnetic dynamics in condensed matter. Our primary goal is to understand such processes at the combined atomic and ultrafast spatiotemporal scales, and we actively develop and apply methods of time-resolved electron microscopy in order to uncover new experimental parameter space and probe fundamental phenomena at the nanoscale. Please visit our Research page for summaries of active projects in the group falling under the general theme of time-resolved and ultrafast electron imaging, diffraction, and spectroscopy.
