Research Areas
The science and technology of nanostructures, particularly carbon-based systems such as nanotubes and C₆₀ molecules; novel fabrication techniques at the nanometer scale; scanned probe microscopy of nanostructures; assembly and measurement of chemical and biological nanostructures.

Current Research
Our research focuses on the fabrication and study of nanostructures – solids that possess structure on the nanometer scale. These structures are small enough to exhibit quantum effects in their electronic and mechanical properties, and yet are large enough to be constructed to a desired size and shape. They thus offer unique opportunities to perform “do-it-yourself” quantum mechanics experiments, and they may have important technological applications. Current areas of interest include carbon-based nanoelectronic devices (nanotubes, buckyballs, etc.), nanomechanics, and nanobiology.
