Small crystals.
Complex instruments.
Better measurements.

We develop electron diffraction, imaging and simulation methods to reveal structure in small crystals and beam-sensitive materials.

Our work connects the experiment, the microscope and the analysis. We combine electron crystallography and coherent imaging with models of electron optics and detector response, and build open-source tools that make microscopy easier to learn and use.
