Prior Works

Green Data Center Design: leveraging cross-layer power management solutions that span software, hardware, and renewable energy systems to improve the sustainability of data centers.

This work leverages promising renewable energy technologies and emerging hardware/software techniques to tackle the energy and environmental challenges faced by computers today and tomorrow. Prior energy-efficient designs mainly emphasize reducing power consumption or improving resource utilization; they are unaware of the behaviors of renewable power supply. By considering the interplay between power systems and computing systems, I have developed several key power management strategeis that enable highly efficient green data centers. Many of my ideas are published on top conferences such as ISCA, HPCA, MICRO, etc.
