Hello!

👋 I am a Ph.D. student in Electrical and Computer Engineering at the University of Minnesota Twin Cities, advised by Professor Zhenman Fang. My research lies in FPGA-based AI accelerators, High-Level Synthesis (HLS) physical co-optimization, and design space exploration.

Prior to starting my Ph.D. at UMN, I built a strong professional background in ASIC design, working as an SoC RTL Engineer at Anapass Inc. where I contributed to over 5 mass-production tape-out projects. This role also served as my alternative mandatory military service required of all Korean men. I received both my B.S. and M.S. degrees from Sungkyunkwan University (SKKU), where I conducted research on DRAM reliability under Professor Jungrae Kim.

In my free time, I love playing sports, particularly running, baseball, and soccer.

Work Experience

SoC RTL Engineer @ R&D Center, Anapass Inc.

Jan 2023 – Jun 2026, Seoul, Korea

• Served in this position as an alternative to the mandatory military duty required of all Korean males.
• Products: OLED TCON/TED ASICs developed in collaboration with Samsung Display and adopted in major consumer devices such as Steam Deck and Samsung Galaxy-A series (5+ mass-production tape-outs).
• Primary responsibilities centered on DFT, DSC codec, and Gate Pulse I/O, with a working understanding of both eDP and MIPI interfaces.
• Played a key role in resolving yield-loss issues via post-silicon debugging, working closely with manufacturing teams.

	SEC-BADAEC: An Efficient ECC With No Vacancy for Strong Memory Protection Yuseok Song, Sangjae Park, Michael B. Sullivan, Jungrae Kim IEEE Access, Vol. 10, 2022 We propose SEC-BADAEC, a zero-vacancy on-die Error Correction Code (ECC) that corrects both single-bit errors and byte-aligned double-adjacent errors (BADAEs) without additional redundancy.
