I am currently a staff research scientist in High Performance Computing Group at Pacific Northwest National Lab (PNNL). I got my Ph.D. in Computer Science from Virginia Tech in 2013. Before joining PNNL HPC group in May 2013, I have worked as R&D intern with several government and industrial  labs including Center for Advanced Computing (CASC) at Lawrence Livermore National Lab (LLNL), Performance Analysis Lab (PAL) at Pacific Northwest National Lab (PNNL), and the Architecture Research Division at NEC Research American at Princeton.

I was a 2011 Livermore ISCR scholar, recipient of 2011 Paul E. Torgersen Excellent research award and 2016 PNNL PCSD outstanding performance award.  I have published in the major HPC-related conferences including ASPLOS, HPCA, PACT, HPDC, ICS, SC and IPDPS, etc. My SC'15 paper is nominated for best student paper runner-up. I serve as organizing committee or PC member for several major HPC venues including ASPLOS, SC, ICS, IPDPS, HPDC, etc. My past and current research are funded by several major government agencies including DOE ASCR, DoD, DoD DARPA and Lab LDRD.  In the past, I have collaborated with both academia and industry labs (e.g., Intel lab and NVIDIA research). 


My research interests lie in several areas of High Performance Computing (HPC):
  • Performance and Energy evaluation and optimization for large-scale HPC systems
  • Heterogeneous programming systems
  • Emerging HPC architectures (e.g., emerging many-core accelerators, memory architectures and machine-learning architectures)
  • Accelerator-Supported acceleration toolset for machine learning and big data applications 
  • Approximate Computing, Accuracy-Aware Computing
  • Big data analytics, Deep Learning, and Dynamic modeling techniques 
  • Fault tolerance and system reliability
