BRIEF BIO:

I am an assistant professor at Erick Jonsson School of Engineering and Computer Science in The University of Texas at Dallas. Before joining it, I earned Ph.D. in computer science at Pennsylvania State University (Advisor:Mahmut Kandemir) and master of science in computer science from Georgia Institute of Technology (Mentor:Sung Kyu Lim, Hsien-Hsin S. Lee and Joonhyuk Yoo). As a guest research scientist (Mentor: John Shalf), I am also co-working with Lawrence Berkeley National Laboratory to model and simulate diverse memory technologies on scientific applications in designing energy efficient Exascale computing systems. In addition to these academic activities, I have 6+ years industry experience, several industrial U.S. patents related to multi-channel SSDs, and approximately thirty technical papers regarding SSD flash firmware and kernel-level file systems.

RESEARCH INTEREST:

I love memory and storage systems. My research topics are mainly focused on advanced computer architecture, embedded systems, firmware, middleware, memory controller design atop/within storage class Non-Volatile Memory (NVM) technologies such as NAND flash, Resistive RAM (RRAM), Magnetic RAM (STT-RAM), and Phase-change RAM (PCRAM). These emerging NVM studies will define new computer architecture and new parallelism computing, which can in turn boost performance and reduce energy consumption with better reliability at a given technology. I am actively leading diverse NVM projects such as modeling open source-based NVM simulation, analyzing/designing high performance many-chip Solid State Disks (SSD), developing host-local NVM systems and optimizing NVM software stacks. I am also interested in introducing different types of NVM technology into scientific applications such as out-of-core computing, in-situ analysis and message logging, and enabling NVM-based burst buffer/micro-check pointing under diverse high performance computing (HPC) and data-center system organizations.
