I’m a graduate student in Computer Science and Communication Engineering at Waseda University, affiliated with the Advanced Multimedia Systems Lab. My research focuses on image recognition (pose estimation) and image generation (human image synthesis). I have hands-on experience fine-tuning generative models such as Stable Diffusion and ControlNet, and I have also worked on building multi-agent AI systems using LLMs. I’m deeply interested in Machine Learning and Software Engineering.
