Nae Young Song (Ph.D.)
Hi All, this is Nae Young Song.
I'm a software engineer at Zoom Video Communication inc. I received my Ph.D degree in Computer Science & Engineering from Seoul National University in 2018. My research areas consist of everything about the storage systems, including filesystems, non-volatile memories and virtual memory subsystems. Please take the time to read this page, and if you want to discuss something with me, please don't hesitate to contact me. :)

Research Area
I've been trying to reduce the software overhead between storage systems and applications, which may be caused when we use high-performance storage devices, to deliver the real performance of storage to applications. The "software" includes every layer between storage and applications. Research Area Keywords are like these :
Filesystem or device driver for New emerging storage devices such as non-volatile memories
Memory management such as paging mechanism,
Distributed computing systems
Skills : (Expert) C, Linux Kernel, C++ (Intermediate) Java, Python, Shell script
Education
Ph.D in Computer Science & Engineering : Seoul National University in 2018.08.
Ph.D Thesis "Efficient Data Management Schemes for High-Performance Storage Devices."
M.S in Computer Science & Engineering : Seoul National University in 2012.08.
B.S in Computer Science : Sookmyung Women's Univeristy in 2010.02.
