About
Hello! I am a Principal Researcher at AIM Intelligence, working on multimodal safety, responsible AI, and large language models (LLMs). I recently completed my M.S. at Yonsei University and an active researcher at HAE-RAE, an open-source research community focused on Korean NLP.
My research spans safety evaluation, alignment, bias mitigation, and adversarial robustness across multimodal and language models.
