I study how to build efficient yet powerful LLMs for real-world practicality.

I am a Ph.D. candidate in Artificial Intelligence at Ajou University, advised by Prof. Jongbin Ryu. My work sits at the intersection of natural language processing and systems: architecture compression, on-device inference and acceleration, and hyperdimensional computing as a hardware-friendly substrate for learning.

News

  1. Two papers accepted to EMNLP 2026: Layer-wise Curriculum Learning for Efficient LLM Compression and Train Overcomplete, Deploy Compact.

  2. Submitted a patent on layer-wise curriculum learning for efficient LLM compression.

  3. Appointed to an instructor for Efficient LLM Research program.

  4. Started the Ph.D. program in Artificial Intelligence at Ajou University, advised by Prof. Jongbin Ryu.

  5. Received a B.S. in Electronic Engineering from Ajou University.
