In-Situ Characterization and Nanomechanics

Current research interests are on in-situ transmission electron microscopy (TEM) to study the nanoscale mechanisms that relate structure to properties for solid-liquid interfacial reactions.

Development of new instrumentation for controlled environmental mechanical testing within the TEM, investigation of chemical-electrochemical-mechanical processes within materials at nanoscale
Quantitative electrochemical testing (organic electrolytes, ionic liquid electrolytes, and solid electrolytes) on individual nanostructures
Observation of nanoparticle assembly and growth in a liquid environment
Corrosion mechanisms of real materials at the nanoscale
Beginning work on Environmental TEM, study of catalyst nanoparticles and gas-reactions at solid surfaces
