Atsuyuki Miyai 宮井 淳行

I'm Atsuyuki Miyai. Now, I'm a 2nd-year PhD student of the Yamasaki Lab at The University of Tokyo 🇯🇵.

Before that, I received my master degree under the supervision of Prof. Kiyoharu Aizawa at UTokyo. With his retirement approaching, I have moved to the Yamasaki Lab, but I will continue collaborative research with the Aizawa Lab and tackle with the same research topic.

My research focuses on the safety of foundation models. Topics that I currently focus on are safety aspects on Multimodal LLM/Agents. Previously, I have contributed to the development of the field of Out-of-Distribution Detection for Vision Language Models (LoCoOp) and the evolution to Large Multi-modal Models (UPD).
I also aim to contribute to recent efforts for the hallucination issues and the development of multilingual LMMs (in a Japanese part), to help realize a future where many users can trust and comfortably use AI systems.

I want to put an emphasis on defining new problems and aim to provide a simple and baseline approach to give insights.

I am seeking internships in industry or academia in 2025, focusing on the trustworthy LMMs/LLMs. Do not hesitate to contact me if there's a good fit 🤝.
