The Efficient Computing Group (ECG) develops efficient technologies for future computing, communication and interfacing. In the recent years, we have focused on mobile systems. It is our mission to provide enabling technologies for mobile systems in another decade beyond form factors like smartphone and tablet. Our current research projects include system software, wireless subsystems, and hardware architecture.

The Efficient Computing Group is led by Prof. Lin Zhong and is located in Duncan Hall. The research laboratory is located in 3039 Duncan Hall.

  • If you enjoy building systems and find our recent work interesting, contact any of us for opportunities in undergraduate and graduate research assistantships.
