Biography

I am currently a staff software engineer at Dell EMC. I was a PhD candidate at the University of Minnesota in the Department of Computer Science and Engineering. My advisor is Dr. David Hung Chang Du. I was working as a research assistant in Center for Research in Intelligent Storage. My research interests include parallel I/O, high performance storage system, workload characterization, and new storage media such as shingled magnetic recording (SMR) drives.

    I was working to develop a high fidelity I/O workload replay engine, in the Advanced Development Department of Array Product Group. We defined high fidelity as being able to provide extremely high workload injection rate to the array controller, as well as the capability to preserve precise arrival pattern and inter-request dependencies as the same time.
  • Dell | Compellent, Summer 2013
    The project is about storage center I/O workload capture, replay and analysis. I was working in the core software team to build a workload recorder inside the storage center. The recorder aims to capture IO requests at different software layers, including virtulization, RAID, and disk manager, etc.
