A note to student applicants:
My research group studies topics which are diverse and cut across many disciplines. As such, few if any of my most successful students had direct experience with every aspect of the research we do here. Rather, they have the passion and drive to expand their own horizons and learn what they need to be successful. Come prepared with a strong foundation in computer science & engineering and you will be given the chance to master the rest. Best wishes!
The Self-Assembled Systems Group studies the design and fabrication of nanostructures as applied specifically to the fabrication of future computing and sensor systems: devices-to-computer architecture. The terms 'nanocomputing' or 'molecular computing' refer to the fabrication techniques (e.g., self-assembly) that have the potential to create devices with critical dimensions near the molecular scale (i.e., < 10nm). However, defects introduced during self-assembly and device operation require a change in the way we design and build these systems.
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.
