Joontaek Oh

Research Associate at Dep. of EE in KAIST

I am a Research Associate in the Department of Electrical Engineering at KAIST. I am a member of Operating Systems Laboratory (OSLab) led by Prof. Youjip Won. I am interested in Linux kernel as whole including the IO subsystem and the Memory Management System. I am focusing on the emergence of a manycore server and a high-performance storage and researching the system software on the manycore server or the high-performance storage. I can be reached at na94jun at kaist.ac.kr or na94jun at gmail.com. My detailed cv is here.

I am looking for a postdoc position.
