| | The Institute for Intelligent Systems (IIS) is designed to bring together research and training in the broad areas of cognitive science, complex dynamical systems, artificial intelligence, and massively parallel computing. We also study the structure of interfaces and nanoparticles. The performance of electrochemical sensors in biomedical applications depends crucially on the characteristics of the space charge layers formed on both sides of the interface with the sample as well as the transport and storage of charged and uncharged species at the interface. The electrical, mechanical, and other properties of nanoparticle composites likewise depend on the space charge layers near the surfaces of the component nanoparticles, with the interesting possibility that bulk electroneutrality exists nowhere inside the particles. Our work is theoretical and computational. In additional to mathematical modeling of space charge structures, we have capabilities for nonlinear least squares fitting and interpretation for impedance measurements made on experimental systems. Current research projects include DNA computing, artificial intelligence, diffusion in confined geometries, structure of interfaces and nanoparticles, solid-state ionics, and chemical thermodynamics. |
