Energy and reliability aware system design

For electronic systems, energy/power consumption and reliability are critical concerns due to their impact on the system cost and the environment. My work exploits characteristics of both applications (such as real-time control and multimedia) and underlying hardware (such as GPUs and heterogeneous multi-core SoCs) to design online and offline techniques to reduce energy and improvement reliability. Below are some representative papers:

My former Ph.D. student, Gang Quan, and I received the Best Paper Award from 2001 Design Automation Conference for our work on power-aware scheduling for fixed-priority real-time systems. Another paper co-authored by us was recognized as one of the Most Influential Papers of 10 Years at 2007 Design, Automation, and Test in Europe Conference (DATE).

In a related research area, I have worked on acceleration techniques for computational problems that arise in medical applications. For instance, I have studied problems in radiation therapy, a minimally invasive surgical procedure that uses a set of focused beams of radiation to destroy tumors. My students, colleagues and I have introduced novel algorithms as well as GPU and FPGA based acceleration approaches for radiation treatment planning, radiation dose calculation and deformable image registration.
