Background

Ryan is the interim group leader for the HPC Core Operations Group at the Oak Ridge Leadership Computing Facility. His group is responsible for delivering highly-scalable and reliable Linux Infrastructure, Networking, and Security services to the high-performance computing resources found in the Supercomputing network.

Previously, he was a Senior Security Engineer at the Oak Ridge Leadership Computing Facility where he spent 10 years coordinating incident detection, security system deployment, security policy development, and supercomputing security architecture.

His background in Linux systems administration at scale helps him understand the nuances of system complexity that is often made worse by sub-optimal security mandates. Overall, Ryan enjoys tackling technical challenges and tries to find creative ways to safely and efficiently enable research when OLCF security policy, technical computational limitations, or other roadblocks chafe against the OLCF research mission.

He is currently interested in understanding how to secure cloud compute platforms such as Kubernetes and OpenShift to an enterprise standard. He also develops and maintains an open source, PIV compliant, secure password management and distribution tool called pkpass. Additionally, Ryan is one of the primary proponents of a message based log aggregation platform to help OLCF collect instrumented system data and deliver it to consumers that can influence decision making, reporting, and security policy.

He holds a masters degree in computer science from the University of Tennessee. He is a certified GIAC Exploit Researcher And Advanced Penetration Tester and has taught several computer hardware and Linux systems administration courses at Pellissippi State Community College as an adjunct faculty member.
