Kevin (Kai-Wei) Chang

I am a PhD student in Electrical and Computer Engineering Department at Carnegie Mellon University, where I am advised by Professor Onur Mutlu. My current research interest is on designing energy-efficient and high-performance computer systems.

Before joining the SAFARI research group, I also graduated from Carnegie Mellon University with an Integrated M.S./B.S. degree in Electrical and Computer Engineering in May 2011.
