Our group at Southern Illinois University conducts research primarily in the field of computational nanoelectronics that involves multiscale modeling of dynamically coupled charge, phonon, and photon generation and transport processes in novel electronic, photonic, and energy-harvesting semiconducting devices. The goal is three-fold: a) understand the fundamental physical processes; b) examine and use the additional degrees-of-freedom accessible at the nanoscale for the improvement of devices' performance and reliability; and c) develop cyber-enabled community nanoelectronics simulation software. We heavily rely on cutting-edge high-performance computing clusters, distributed CPU/GPGPU computing platforms, and innovative algorithms.
