Kathryn Mohror is the Group Leader for the Data Analysis Group in the Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory (LLNL). Kathryn’s research on high-end computing systems is currently focused on scalable fault tolerant computing and I/O for extreme scale systems. Her other research interests include scalable performance analysis and tuning, and parallel programming paradigms. Kathryn has been working at LLNL since 2010.

Kathryn works closely with the Development Environment Group (DEG) in Livermore Computing (LC). Her current research focuses primarily on scalable user-level file systems and the Scalable Checkpoint/Restart Library (SCR), a multilevel checkpointing library that has been shown to significantly reduce checkpointing overhead. She also leads the Tools Working Group for the MPI Forum.

Kathryn received her Ph.D. in Computer Science in 2010, an M.S. in Computer Science in 2004, and a B.S. in Chemistry in 1999 from Portland State University (PSU) in Portland, OR.
