Hey! Welcome to Junryu's website!

About Me

I'm from Yokohama, Japan. My background is in Civil Engineering, specifically in Construction Engineering and Management, and Machine Learning. I am interested in changing an industry that is spiraling into its most uncertain age due to labor shortages, rising costs, and increased demand for building new buildings as well as maintaining old buildings and infrastructure. My current focus is advancing MLLM capabilities for construction specific domains.
