Ryugo Morita

I am a PhD student at RPTU Kaiserslautern-Landau and DFKI, and a visiting researcher at Hosei University and Osaka Metropolitan University. My research focuses on image/video generative models, especially for layer-wise image generation and editing. I am also interested in AI-driven education and how generative AI can augment human creativity and learning.
