My research focuses on networked real-time embedded systems for sensing and control applications. We are seeing an increasing number of new systems that interact directly with the environment where poor performance, unanticipated results and failure can be catastrophic. In the spirit of systems research, I like to design, implement and evaluate these types of systems in order to truly understand them.

Recently, I have been working on developing large-scale sensor networks and their supporting technologies that are energy-efficient and provide real-time properties. Sensor networks are a practical mechanism for bringing contextual information and new abilities to the already numerous embedded systems that surround us. They have the potential to revolutionize a wide range of application areas ranging from transportation and critical infrastructure monitoring to smart buildings and microgrids. One of our core focuses is on precise timing and navigation to support localization in GPS-denied environments like inside buildings.
