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

Atomic-Scale Defects & Interfaces
We investigate point defects, light elements, interfaces, and local structural distortions, revealing how atomic-scale structure governs material properties.

Functional & Quantum Materials
We use advanced microscopy to uncover structure–property relationships in superconducting, magnetic, ferroelectric, and other functional and quantum materials.

Nanoscale Electromagnetic States
We image and manipulate nanoscale magnetic and electromagnetic states, including domain walls, skyrmions, and topological textures using advanced and in situ microscopy.
