Emine Ugur Kaynar

I have just receieved my Ph.D. (May 2022) from the Department of Computer Science at Boston University. I am working with Prof. Orran Krieger, Prof. Larry Rudolph and Prof. Peter Desnoyers.
I’m a member of the Systems Research Group, and associated with Mass Open Cloud and Red Hat Research.

My research interests lie broadly in the fields of storage systems and cloud computing.
Currently, my research is focused on storage-related topics including caching systems, object storage, erasure coding and distributed storage systems.

Education

  • Ph.D. in Computer Science - Boston University, May 2022
    • Dissertation: Cooperative Caching for Object Storage (Advisor: Orran Krieger)
  • M.Sc. in Computer Science - SUNY at Binghamton, August 2013
    • Thesis: Impact of Encryption on Live Virtual Machine Migration (Advisor: Ping Yang)
  • B.Sc. in Information Systems Engineering - Bogazici University/SUNY at Binghamton, May 2011

Selected Research Projects

  • D4N (Directory Based D3N) is a directory-based cooperative cache that provides a distributed directory for a global state, re-uses the existing data lake (Ceph) software for implementing a write tier and exploits the semantics of immutable objects to move aged objects to the shared data lake.
    We are still in the process of upstreaming the D4N and convincing the Ceph upstream community.

  • D3N (Datacenter-scale Data Delivery Network) is a multi layer cooperative caching extension to storage system itself as a solution to network constrained data centers. D3N has been upstreamed into the Ceph code base by Red Hat and is available as an experimental feature in Ceph today.
