Research Area: Syntactic Parsing, Text to Image Generation
My CV is available here (last modified: Apr. 4, 2024).


I am currently a doctoral student in the Graduate School of Information Science and Engineering at Ritsumeikan University, where I am conducting research on natural language processing and computer vision using deep learning. Within the field of natural language processing, I specialize in syntactic parsing, and my current work involves fundamental research on integrating syntactic parsing techniques with large language models and image generation models. In my research, I aim to realize human-specific cognitive functions (e.g., creative aspects of natural language) using computers, and I am also strongly interested in applying natural language processing and other deep learning-related technologies to actual social problems and business.
