Luanzheng "Lenny" Guo

I am a staff computer scientist working with the HPC Group at Pacific Northwest National Laboratory, especially in the research area between Scientific Computing, Data Science, and HPC. Previously, I obtained my Ph.D. degree in Electrical Engineering & Computer Science from the University of California-Merced, focusing on HPC systems. Since joined PNNL in 2020, he has spanned his research focus to interdisciplinary research, including scientific workflow coordination across HPC, Cloud, and Edge, power-grid computing system resilience, scientific data reduction/compression, generative AI for science, and physics-informed AI. My research has been highlighted by HPCWire in its “What's new in HPC research” in 2018 and 2020. I am an NSF Cyberinfrastructure (TrustedCI) Fellow in 2020.
