My group studies the design, synthesis and properties of nanostructures for future computer and sensor systems. Specifically, we use DNA self-assembly, a bottom-up fabrication technique that can be used to achieve molecular scale resolution, to build experimental devices which we then characterize using a variety of tools from nanoscience. Connecting this research to the real world requires us to adopt a broad and vertical research approach that employs computational modeling and analytical theory to demonstrate how the unique properties of the systems we discover, and engineer, can best be used. Work in this area of nanoscience is exciting, cross-cutting and requires students to engage in subjects far beyond traditional areas of computer science and engineering.
Self-assembly is a bottom-up fabrication technique that can be used to achieve molecular scale resolution. Some of the images to the right are atomic force microscope (AFM) images of several nanostructures that we have fabricated in our lab. The goal is to use these structures to integrate active nanoelectronic devices into a fully self-assembled circuit technology - and to study the new forms of computer architecture that the technology enables. To do this we have adopted a broad and vertical research approach to cover topics in the synthesis and design of DNA nanostructures, nanoscale device and circuit modeling, and studies of emerging computer architectures. We are also interested in expanding the domain within which computing can be applied, specifically into biological and physical environments.
