Ultrafast Electron Microscopy of Molecular and Materials Dynamics
The Flannigan Group seeks to answer fundamental questions about energy movement and redistribution in nanoscale systems by developing methods to uncover new physical insights on ultrasmall and ultrafast spatiotemporal scales.

Our general approach involves working at the intersection of materials science, physical chemistry, and condensed-matter physics to develop new ways of studying lattice and molecular, electronic, and magnetic dynamics spanning a broad range of space and time. In this way, we aim to develop a rich, comprehensive picture of energy processes - from the level of atoms and charge carriers up to classically-described nanomechanics. Central to our methods is the development and application of novel time-resolved techniques, such as ultrafast electron microscopy, in order to gain access to largely unexplored parameter space.
