profile


I am a data storage researcher at IBM Almaden Research Center. I hold a Ph.D. degree in Computer Science from Stony Brook University (SBU) and M.S. degree in Applied Mathematics and Physics from Moscow Institute of Physics and Technology (MIPT). In my earlier years I worked as a kernel engineer at Parallels.

My research interests revolve around high-performing local and distributed storage systems. I'm especially interested in workload characterization and performance analysis of complex storage systems in diverse modern evironments. I work closely with the IBM Spectrum Scale (aka GPFS) development and support teams which gives me a unique exposure to the problems encountered by storage systems in the real world.

Among the active directions of my research are

  • Efficient storage for Docker containers
  • Object-backed file systems
  • Scalable trace analysis and low-overhead tracing of highly distributed systems
  • Performance analysis of user-space file systems
  • Root cause analysis of performance and resource utilization in modern I/O stacks
  • I/O stack design and tuning for low-latency storage devices
  • Performance modeling of storage systems
  • Data deduplication

You can find the list of my publications and patents in the corresponding sections. I actively collaborate with academic community and regularly serve as a reviewer for major storage conferences and journals.
