Geuntaek Lim

I am a Ph.D. student in Artificial Intelligence at Sejong University, advised by Prof. Yukyung Choi. Recently, I was a research intern at NAVER Cloud.

My research centers on multimodal AI with a particular emphasis on video-centric modeling. My goal is to empower AI systems to assist humans in interpreting complex video content.
