Advanced Electron Microscopy Lab

Seeing materials at the atomic scale

Developing advanced electron microscopy to reveal atomic structure, defects, and electromagnetic states in materials and devices.

About Our Lab

Exploring materials across scales.

We develop advanced electron microscopy techniques to understand emerging phenomena in condensed matter physics and materials science, from the micron to the atomic scale.

Our research combines 4D-STEM , electron ptychography , quantitative imaging, and in situ microscopy to investigate interfaces, defects, functional and quantum materials, and nanoscale electromagnetic states.

Research Areas

Imaging, structure, and emergent states

We develop advanced electron microscopy methods and apply them to understand materials from atomic structure and defects to functional properties and nanoscale electromagnetic states.

4D-STEM & Electron Ptychography

4D-STEM & Electron Ptychography

We develop advanced 4D-STEM and electron ptychography methods for high-resolution, dose-efficient, quantitative, and three-dimensional imaging beyond conventional electron-optical limits.
