Inho Song
I am a Ph.D. student in Computer Science at Virginia Tech, co-advised by Huaicheng Li and Sam H. Noh. My research centers on software/hardware co-design for low, predictable end-to-end latency and high throughput in modern storage systems — spanning SSD internals (FDP, ZNS), file systems, and the interfaces between them.
Before Virginia Tech, I earned my M.S. (2023) and B.S. (2022) in Computer Science at Dankook University in Korea, advised by Jongmoo Choi. My master’s thesis studied the design tradeoffs in ZNS SSD performance. In Summer 2024, I interned with Samsung Electronics on the Controller Architecture Team (CAT) in San Jose, modeling HW-SW co-design solutions for NVMe FDP storage.
Research interests
