About Me

👋 Hello, I am Dongjae Kim

Market Simulation Architect and LLM Agent Researcher at National Pukyong National University, South Korea 🎓

My research captures dynamics of EMERGING TECHNOLOGY MARKET by analyzing both its SUPPLY and DEMAND sides.

1. The Supply Side 🛠️

I identify technological trajectories and convergence to trace innovation evolution using semantic main path analysis.

2. The Demand Side 👥

I investigate how emerging technologies reshape consumer behavior and market structures.

I’m focusing on simulation of human decision-making and cognitive reasoning processes with LLM agents.
