Jae-Seung Yeom is a computer scientist at the Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory. His current research focuses include:

• Intelligent orchestration of scientific workflows over heterogeneous compute resources and platforms
• Convergence of the Cloud and HPC in supporting scientific workflows
• Autonomous multi-scale simulations using ML
• Managing data-dependence in scientific workflows

Additionally, since joining the Lab in July 2014, he has been working on various research projects:

• Scaling the performance of deep learning on HPC platforms
• Detecting objects of interest in radiographic images
• Modeling the multi-scale evolutionary dynamics of RNA virus populations using optimistic/reversible parallel discrete event simulations
• Large scale agent-based epidemiological simulation with co-evolving networks of dynamically interacting populations
• Data-driven modeling and optimizing the performance of solver libraries for sparse linear systems

He contributes to Flux, a hierarchical workload management system for scientific computing workloads, and LBANN (Livermore Big Artificial Intelligence), a deep learning training tool kit for HPC.

Jae-Seung obtained his Ph.D. from Virginia Tech in May 2014, and M.S. from Carnegie Mellon University in 2003. He holds B.S. degrees in Astronomy and Computer Science obtained from Yonsei University, South Korea.
