About us

Located at both UC Berkeley and Berkeley Lab, we are a research group led by Andrew Minor that uses advanced electron microscopy to investigate both organic and inorganic materials.

Our focus is on nanomechanical size effects, the characterization of soft materials, and new in situ TEM methods for materials science. Professor Minor is also Facility Director of the National Center for Electron Microscopy at the Molecular Foundry, Berkeley Lab.
