Curriclum Vitae

I am a postdoctoral researcher in the Institute of Computer Technology at Seoul National University. I was advised by Prof. Sang Lyul Min, and my thesis explored granting autonomicity to SSDs for making performance more predictable.

My interests include storage systems (particularly flash memory-based), operating systems, file systems, and data-intensive applications such as key-value stores.


Research directions
     Performance-predictable SSD [ATC'18, HotStorage'18, RTAS'17]
     High-performance SSD architecture [under review, TC'11]
     Flash memory errors and SSD reliability [FAST'19]
     Scalable key-value store [SIGMETRICS'19]
