Areas of Interest
Research focuses on studies of interactions between surface and
adsorbate properties that induce morphological transitions, change
electronic characteristics, and determine growth and ordering.
Particular interest lies in studies utilizing scanning probe microscopies
to elucidate mechanisms for surface driven phenomena, single molecule
behavior, molecular junction characteristics, as well as the development
of novel instrumentation for interrogating nanoscale structures
at the atomic and molecular level. More information available: Pearl
