I am an assistant professor in the Department of Electrical and Computer Engineering at the Texas A&M University where I am a member of the Computer Engineering group.  I lead the CAMSIN research group, where our research focuses on power, reliability and performance of the future chip-multiprocessor (CMP) and multiprocessor system-on-chip (MPSoC). I received my PhD in Electrical and Computer Engineering from the University of Texas at Austin, December 2008.  On the TRIPS prototype processor project I designed, implemented and verified the second level memory system, on-chip network and chip-to-chip network.

Research Interests
