Ph.D., Georgia Tech, 2013

    My research interests are in compilers and computer architecture with an emphasis on performance, reliability, and security. I have developed program analysis and microarchitecture optimization techniques for soft error resilience, concurrency bug detection, and system security such as memory safety and Linux kernel permission check. Currently, I am working on energy-efficient intermittent computation and nonvolatile memory crash consistency. To come up with cost-effective solutions, I often leverage compiler-architecture codesign and repurpose existing hardware features.

    Prior to joining Purdue, I was an Assistant Professor at Virginia Tech which I joined after completing my PhD under the supervision of Prof. Santosh Pande at Georgia Tech in 2013. During the three summers between 2010 and 2012, I worked as a software engineering intern with the compiler optimization team at Google. From 2005 to 2008, I was a member of the research staff at ETRI (Electronics and Telecommunications Research Institute). I was honored to receive an NSF CAREER Award (2018) and inducted into MICRO Hall of Fame (2021).

    My lab, the CompArch (Compiler and Architecture) research group, was formed in 2013 at Virginia Tech and is now at Purdue. CompArch focuses on compiler-architecture cooperation, compiler optimization, and computer architecture exploration to address cross-cutting concerns involving performance, reliability, and security. The following two logos were designed by my two daugthers Hannah and Chayah, respectively.
