Research Areas
Spectroscopic techniques are used to probe the dynamical properties of intrinsic localized modes: in micromechanical arrays, in anharmonic crystals and in magnetic solids.

Current Research
The exploration of energy localization in discrete nonlinear lattices, both classical and quantum mechanical, is an ongoing focus. A holographic Fourier transform spectrometer is being developed for single shot electron bunch length measurements.
