In general, our research is focused on the development of novel ways to perform computation. Our research is highly interdisciplinary in nature, spanning across material science, physics, electrical engineering and computer science, and involves both theoretical and experimental work. This includes development of functional materials and investigating physical principles to implement novel electronic devices, exploration of novel high performance circuit architectures for general purpose and application specific tasks, and development of relevant algorithms and software tools. Our current research focus is on resistive switching ("memristive") effect in metal oxide thin-film devices and its applications in computing, specifically in the context of CMOL circuits.
