  • Profile

    I am an experimental physicist, and my research focuses broadly on physics and applications at the nanometer scale.  One particular field of interest is diblock copolymer materials, which can spontaneously self-assemble into periodic structures of cylinders or spheres that are on the order of 10 nanometers across. I use these systems as a laboratory for nanoscale physics, studying how periodic patterns are formed and develop with time, a question central to condensed matter physics and materials science. These materials are also important for applications in nanotechnology, and I am interested in using the patterns they generate as templates for nanoscale lithography, which could help make the next generation of computer chips and storage devices.  A second, more recent area of interest is the formation of “black silicon,” silicon in which the surface has acquired extreme nanoscale roughness from a plasma etching process, leading to extremely low optical reflectivity.  Black silicon also has several potential applications, including possibly use in high efficiency solar panels. 

    The main tool for my work is microscopy.  My laboratory here at Richmond includes a state of the art Asylum Research MPF-3D atomic force microscope, or “AFM.”  I also use scanning electron microscopy (SEM) as well as focused ion beam (FIB) tomography.  A large part of my research program is dedicated to developing new microscopy techniques using these instruments.  I have developed new techniques using computational methods to remove artifacts due to positional drift from AFM images.  I have also developed algorithms and software for creating 3D models from SEM and FIB data.
