Thanh-Long V. Le
I am a M.S. student at KAIST AI, advised by Prof. Eunho Yang and working closely with Dr. Viet Lai from Adobe Research. Previously, I received my B.S. degree in Computer Science at KAIST, advised by Prof. Sung-Ju Lee.
My research centers on large language models (LLMs), with an emphasis on improving their reasoning abilities through reinforcement learning and other post-training techniques. Recently, I have also begun exploring generative modeling, with a current focus on applying reinforcement learning to diffusion and flow models.
Outside of research, I’m deeply passionate about cinema and photography. If you ever find yourself in Seoul, feel free to shoot me an email—we could grab a coffee and yap about AI and movies, or head out for some spontaneous photo-taking!
