Group Photo Summer 2018


The Flannigan Research Group is interested in elucidating the structure-function relationships of nanoscale and nanostructured materials.  To accomplish this, we work at the intersection of materials science, physical chemistry, and condensed-matter physics and focus on the study of fundamental lattice and molecular, electronic, and magnetic dynamics on fast (ms-ns) and ultrafast (ps-fs) timescales.  Our primary goal is to understand fundamental behaviors on the combined atomic and ultrafast spatiotemporal scales, and we actively develop and apply novel methods of time-resolved electron scattering to gain access to unique experimental parameter space.  Please visit our Research page for summaries of currently active projects in the group, wherein we are studying:

  • Energy transport and conversion in archetypal and advanced semiconducting materials, especially related to light-material interactions.
  • Electronic and structural behaviors of plasmonic nanocrystals for catalytic and energy applications.
  • Fundamental theories of transient electron scattering for quantification of chemical and materials properties.
  • Development of advanced techniques for probing electron-matter interactions and for overcoming structural damage.
