I am a PhD student in Computer Science and Engineering at POSTECH, advised by Prof. Eunhyeok Park at the Eco Lab (Efficient Computing Lab), part of the ML Lab.

I started my PhD in 2024 and earned my B.S. in Computer Science and Engineering from POSTECH. I was also an exchange student at Université de technologie de Troyes, France, in 2023.

I am broadly interested in improving the efficiency and performance of AI models through approaches such as model compression and efficient inference. Recently, I have been particularly interested in reasoning in LLMs and how to improve it efficiently. My interests span large language models, looped language models, and spiking neural networks.
