I am interested in how nanostructured materials behave, and how the properties of matter can be tailored by controlling geometry and size at the nano-scale.  Specifically, I work with Scanning Probe Microscopes (SPMs), that allow us to image, manipulate and probe the properties of matter down to the atomic scale.  We have a particular interest in mapping the chemical, electrical and mechanical properties of surfaces spanning the range from hard to soft matter.

We have pioneered several SPM-based techniques including Piezoresponse force microscopy (PFM) and ultrahigh resolution relocation for AFM.

My group is also interested in investigating electrical transport in carbon nanosystems ranging from graphene devices to organic molecules, as they may one day complement traditional semiconductor devices.  Our work covers the range from fundamental to highly applied.
