Scott joined ORNL in 2011 as a HPC Systems Engineer. He is the Team Lead for the System Architecture (SysArch) and Burst Buffer (BB) teams. The SysArch team focuses on system architectures, networking, and scheduling trends and technologies. The BB team has been preparing software to maximize the use of Non-Volatile Memory (NVM) on Summit. These projects will provide easy to use libraries that allow legacy applications to use the BB without major code modifications.

Prior to joining ORNL, Scott worked at Myricom, where his projects included MPICH2-MX, BMI-MX (PVFS2 over MX), MXLND (Lustre over MX), and other projects. Scott had also worked in the Logistical Computing and Internetworking Lab (LoCI) at the University of Tennessee where he focused on distributed storage over the wide-area.
