CV

Welcome to my research profile!

I am a Ph.D. candidate in CILab at KAIST EE, advised by Professor Changick Kim. Previously, I was a research intern at Microsoft Research Asia.

My research focuses on multimodal AI systems that perceive, understand, and act in complex real-world environments. My work spans multi-sensor fusion, vision-language and video understanding, and efficient sequence modeling with state space models (SSMs). More recently, I have been developing benchmarks and evaluation methods for multimodal agents that create and edit real-world documents in applications such as Microsoft Word.

If you are interested in collaborating, feel free to reach out :)
