I’m Byunghee Yoo. I live in Seoul, where I design the future.

I’ve always loved building and fixing things, especially when it comes to making processes smarter or more efficient. My first hands-on experience with technology wasn’t a game or toy, but disassembling and reassembling old computers around the house—curiosity driving me to figure out how things actually worked.

While my classmates were drawing or playing sports, I was sketching out building layouts and imagining how cities could be safer and more efficient if only people worked more like machines—logical, predictable, but always improving. This led me to construction management and engineering, where I became obsessed with risk assessment and safety in complex environments.

In college, I started experimenting with AI, trying to see if machines could predict and prevent the kinds of accidents I saw in textbooks and case studies. My research eventually led me to develop risk assessment models and publish my first journal paper on using large language models (LLMs) to predict construction accidents—complete with explainable AI visualization to help practitioners actually trust what the models were saying.

From there, I’ve presented my work at conferences in Korea and Japan, helped standardize safety documentation for government smart construction projects, and built accident prediction systems that combine domain expertise, legal codes, and machine learning.

Today, I’m focused on blending construction engineering, AI, and risk management—working on practical systems that make construction sites safer and smarter. My goal is to push the boundaries of what’s possible in smart construction, so the next generation of builders and managers can focus on creativity and innovation, not just paperwork and compliance.
