Kathryn's current research focuses primarily I/O performance and portability for HPC. She leads both the Unify project, developing scalable file system support for in-system storage on HPC systems through UnifyFS, and the Scalable Checkpoint/Restart Library (SCR) project, an R&D100 Award-winning multilevel checkpointing library that has been shown to significantly reduce checkpointing overhead. Additionally, she leads the IOPP project, funded by ASCR ECRP, that is working towards fundamental understanding of the needs of current and emerging HPC I/O workloads and developing support based on that understanding.
