Hyukkyu Kang
I am a Ph.D. candidate in the Data Systems Lab at Pohang University of Science and Technology (POSTECH), advised by Professor Wook-Shin Han. My research interest lies in the field of Natural Language Processing (NLP) and Information Retrieval (IR), particularly in developing foundation models with retrieval. I have hands-on experience in pre-training language models and fine-tuning them for downstream tasks such as text retrieval and semantic parsing.
