Research Interests
- Network Modeling: Developing the solution techniques required to improve the efficiency and resilience of transportation networks, such as such as public transit, infrastructure, and logistics in uncertain and unpredictable conditions
- Mobility Service: Developing the real-time operation strategy of mobility services (such as car-sharing, bike-sharing, and ride-sharing) in uncertain and dynamic conditions
- User Behavior: Understanding the characteristics of transportation users’ behaviors (such as mode choice, shortest path algorithm, routing, and driving behavior)
