Dr. Younghun Bahk is an Assistant Professor in the Department of Transportation Systems Engineering at Ajou University. His research focuses on network-based modeling of autonomous vehicle (AV) travel patterns, activity-based routing, and regional transportation planning models. With a long-standing interest in public transit systems, his work often incorporates multimodal components and examines how different modes connect within broader transportation networks. He is particularly interested in intermodal trips and their implications for travel behavior and transportation planning.

He received his PhD in Civil and Environmental Engineering from the University of California, Irvine, where his doctoral research focused on future multimodal transportation systems involving household-owned AVs. He also holds an MS in Urban Planning and Engineering from Yonsei University, where his research examined interlining effects and transfer penalties in urban bus transit systems.
