Interests

I received my Ph.D. in Electrical and Computer Engineering from Seoul National University, where my research focused on image restoration and super-resolution. My academic work includes the widely cited EDSR paper, with over 9,900 citations and 2,600 stars, reflecting both scholarly and community impact.

At TwelveLabs, I build a knowledge-graph-based agentic platform that turns raw video into structured, queryable understanding. I design the system architecture and lead cross-product integrations, while helping accelerate teams and establish an engaging team culture.

Previously at Samsung Electronics, I deployed fine-tuned LLMs to over 10K internal engineers, trained 70B reasoning models across 128+ GPUs, and led cross-functional teams for LLM infrastructure and manufacturing process automation.

I love building things with a team that has great energy. I also find it very rewarding to build systems and tools that make the whole team faster and more efficient. For me, the best part of the job is looking at what we created together and feeling proud of our work. I want to keep building great tech in a fun environment where we can all be excited about what we achieve as a team.
