Senior🎓
Top SchoolRyan Day is an experienced HPC resource management lead at Lawrence Livermore National Laboratory with over a decade managing Slurm, Flux, and LSF deployments for large-scale scientific computing. He combines hands-on operational expertise—configuring, monitoring, and automating scheduler infrastructure—with a strong research background in computational biochemistry and protein structure prediction. Ryan’s scientific training (PhD in medicinal chemistry) informs his pragmatic approach to tooling and large data analysis, and he has written numerous monitoring and notification programs to keep compute centers healthy and users informed. He has a track record of interdisciplinary collaboration across biology, physics, statistics, and computer science, which has produced peer-reviewed publications and driven practical solutions for complex simulations. Known for mentoring users and colleagues, he blends deep domain knowledge in molecular dynamics and bioinformatics with day-to-day leadership of LC resource management. An interesting detail: he transitioned from developing novel protein-packing algorithms to leading production-scale scheduler operations, bridging research software and enterprise HPC administration.
