Research Interests

I am a Computer Scientist at the Center for Applied Scientific Computing (CASC) at the Lawrence Livermore National Laboratory (LLNL), California. My main area of research is high-performance computing (HPC). My main sub-area of research in HPC is programing models and systems.

Specific research interests:

  • Software correctness, debugging, reproducibility, floating-point analysis
  • Compiler instrumentation (LLVM), static analysis, program analysis
  • Fault tolerance, resilience, error data analysis
  • Machine learning and AI applied to programming
