Systems Research

The Systems Research group focuses mostly on the performance and reliability of engineering systems. It focuses on projects that enable new software capabilities important for a RiskOps Platform, and improve systems characteristics such as memory, storage, computation, latency, throughput, availability, cloud cost, reliability and stability, etc.

Research Focus:

  • Streaming Engines
  • Graph-based storages
  • ML infrastructure
  • Distributed processing
