Hi! 👋 I’m Hahyeon Choi, a graduate student at Seoul National University, advised by Prof. Nojun Kwak at the Machine Intelligence and Pattern Analysis Lab (MIPAL). Prior to my graduate studies, I earned my Bachelor's degree in Electrical and Computer Engineering at Seoul National University.

My research interests lie in multimodal representation learning, Mixture-of-Experts, and large-scale model pretraining. I am particularly interested in understanding how model architectures and learning dynamics can enable more effective and scalable learning across diverse modalities.
