Research Overview
The general focus of our research is 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, exploration of novel electronic devices and 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 hardware implementations of mixed-signal artificial neural networks with emerging memory devices.
