Our major research programs are:

• The phase and inverse scattering problem for electrons multiply scattered by solids.

• Inelastic scattering of electrons in crystals: Scattering of fast electrons in crystalline solids; absorptive scattering; nonlocality in scattering, applications to microanalysis.

• Modeling of scanning transmission electron microscopy (STEM) images from first principles.

• Exit surface wave function reconstruction in high-resolution transmission electron microscopy; aberration determination and correction.

• Dynamics and stability of dilute gas Bose-Einstein condensates in optical lattices.

• The breakdown of the integer quantum Hall effect.

• Dephasing and charge fluctuations in mesoscopic conductors.

• This group also hosts a very successful program in nuclear scattering and structure using many body techniques (see Nuclear Structure link for details of research, people and publications).
