Our work on the surface potential of few-layer graphene films is featured as the recent cover article of the January 2009 issue of Nano Letters.

Using electrostatic force microscopy we probe the charge screening features of few-layer graphene films.

The work was performed in collaboration with S. S. Datta, E. J. Mele , and A. T. Johnson.


Crystallographic etching of few-layer graphene which we recently reported in Nano Letters was highlighted by Nature Nanotechnology.

By utilizing metallic nanoparticles, we are able to etch few-layer graphene samples along specific crystallographic directions.

This work was performed in collaboration with S. S. Datta, S. M. Khamis , and A. T. Johnson.

I am a condensed matter experimentalist in the Department of Physics and Astronomy at the University of Kentucky (UK). I am the first faculty hire of the recently formed Center for Advanced Materials at UK. My current focus is on the synthesis and investigation of nanoscale materials.

I have a background in a variety of condensed matter fields, which are useful for my current interdisciplinary research interests. After graduating from Northwestern University in Physics, I attended the University of Maryland where I investigated phase transitions and critical phenomena of high-temperature superconductors with Christopher J. Lobb and Steven M. Anlage in the Center for Superconductivity Research. After receiving my PhD, I was a Chateaubriand Fellow and studied soft condensed matter and colloidal systems at the École Normale Supérieure in Paris for about a year. I then moved to the University of Pennsylvania where I researched nanoscience and technology as a post-doctoral fellow with A. T. Charlie Johnson and Dawn A. Bonnell.
