About Me

I'm an Assistant Professor in the Department of Civil, Environmental, and Geo-Engineering at the University of Minnesota, Twin Cities. I received my Ph.D. from the Department of Civil and Environmental Engineering at Korea Advanced Institute of Science and Technology supervised by Professor Hwasoo Yeo at AIxMobility Lab. I received my Bachelor and Master's degrees from the same department and institute. Also, I was a Postdoctoral Researcher in the Department of Civil Engineering at McGill University in Canada with Professor Lijun Sun's group.

My research interests are broad and interdisciplinary, encompassing Urban Mobility Data Analytics, Spatiotemporal Data Modeling, Deep Learning & Artificial Intelligence, and Connected Automated Vehicles (CAV) & Cooperative-ITS. I am particularly driven by the desire to optimize urban mobility and contribute to the development of a sustainable and efficient urban transportation system. My work involves utilizing data analytics to draw valuable insights from urban mobility data and applying cutting-edge AI technologies in the field of transportation.

My research topics and interests are as follows:

• Urban transportation and mobility data analytics
• Spatiotemporal data modeling (forecasting, imputation)
• Generative AI for transportation and mobility data
• Modeling CAV, C-ITS using Reinforcement Learning
• Other applications of machine learning and deep learning in the transportation domain

For Prospective Students/Postdocs

I am looking for 1-2 PhD students (and/or a Postdoc) for 2025 Spring/Fall (starts in January/September) who are excited about machine learning for urban transportation and mobility data. If you're interested, please send me an email at chois[at]umn.edu. Please include a CV, a research statement, and an academic transcript.
Please use “Prospective PhD student [Your name]” as your email subject. Due to the large volume of emails, I apologize for not replying to individual inquiries I have received.
