ML Systems
Building software systems to improve hardware utilization and serving throughput for emerging AI models.
About
I am an M.S. candidate in the Department of Computer Science and Engineering at Seoul National University. I am fortunate to be advised by Prof. Jae W. Lee, Director of the AI Institute of Seoul National University, and am a member of the Architecture and Code Optimization (ARC) Lab. I also collaborate with Prof. Sehoon Kim, an Assistant Professor at KAIST AI, who co-advises my current research in ML systems.
I am interested in efficient computing through the co-design of algorithms, systems, and architectures. My current research focuses on improving the inference efficiency of diffusion language models and hybrid-attention models through ML algorithm-system co-design. In the long term, I aim to build reliable and efficient long-horizon AI and robotic agents.
Research
ML Algorithms
Designing algorithms for sparse attention and quantization to improve the efficiency of foundation models.
Computer Architecture
Exploring memory, storage, and heterogeneous systems for emerging AI workloads.
