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).
