Principal Investigator

Seongjin Choi

I'm an Assistant Professor in Civil, Environmental, and Geo-Engineering at the University of Minnesota, Twin Cities, working at the intersection of artificial intelligence and transportation — generative models, vision-language-action models, and LLM agents that turn messy city data into operational insight.

Biography.

My research is broad and interdisciplinary, spanning urban mobility data analytics, spatiotemporal data modeling, deep learning & AI, and connected automated vehicles (CAV) & cooperative-ITS. I'm driven by the goal of optimizing urban mobility and helping build sustainable, efficient transportation systems.

My work draws insights from urban mobility data and applies cutting-edge AI — diffusion and flow-based generative models, vision-language-action models, and large language model agents — to real transportation problems.
