About Me

I am Phillip (Yuseung) Lee, a first year PhD student at KAIST Graduate School of AI, advised by Prof. Minhyuk Sung. I received both my Masters and Bachelors degree at KAIST. I was also fortunate to closely collaborate with Prof. Leonidas Guibas.

My research interests revolve around enhancing the spatial control and understanding of large foundation models. Specifically, I have worked on advancing the 3D spatial reasoning capabilities of vision-language models (VLMs), and enhancing the spatial control of diffusion models for image generation.

I am open to internship and collaboration opportunities! Please feel free to contact me via email. My CV is at Curriculum Vitae (CV).
