Welcome to the Synergy website

The Systems, Networking, and Energy Efficiency (Synergy) lab is at the School of Computer Science, at Carnegie Mellon University. It is led by Professor Yuvraj Agarwal. Our lab was started by Yuvraj at UC San Diego and we continue to have close ties and collaborations with colleagues in that department, including the MESL Lab.

Our research focus is on designing systems with the goal of improving energy efficiency at all levels. As such many of our research projects span hardware systems (embedded/sensors) and software systems with students acquiring experience in either or both areas. We focus on project with a high societal impact and relevance and aim to develop and deploy our resarch at scale. Recent examples include multiple Smart Building related projects that have been deployed across a Building (Occupancy based control, SleepServer, Sentinel) and at a campus scale at UC San Diego (Energy Dashboard). Another example is our ProtectMyPrivacy project currently in use by over 150,000 iOS users!

Our lab is located in Wean Hall (3rd Floor, Room 3306) at CMU. Some of our existing students on the UCSD campus are located in CSE 2113. Dr. Yuvraj Agarwal's office is in WEAN Hall @ CMU, Room 5313.

About Our Logo

Our logo consists of three hexagons, each repesenting a focus of our efforts. The top represents the hardware of our systems, the bottom represents the software that runs our systems, and the right represents that our systems are meant to make positive contributions to energy management and make the world a "greener" place. Thus our driving force is the synergy of these three.
