Hi there, I am Rusi Wang (Chinese name: 王铷锶), and you can call me “Royce”. I was born in February 1999 in Shanghai, China. I am currently a Ph.D. candidate at the Urban Mobility Institute, Tongji University.

I have been fascinated by maps since childhood. During my undergraduate studies at the University of Electronic Science and Technology of China, a course sparked my interest in studying networks. This interest has since grown into my research on transportation network modeling and optimization.

I began my Ph.D. research in August 2024 under the supervision of Professor Chi Xie, focusing on network modeling and optimization. My work with Professor Xie has included network equilibrium modeling in freight transportation networks and dynamic multimodal traffic networks. A key contribution of my work is the development of an analytical dynamic traffic assignment (DTA) model that is computationally tractable for large-scale networks and accommodates multimodal transportation (e.g., solo driving, e-hailing, carpooling, public transit, and combined modes). Following Professor Xie’s move to a new academic position, Professor Yuntao Guo became my doctoral advisor at Tongji University. I continue to work with Professor Xie on research begun under his guidance.

I am now working with Professor Guo on the research that will form my doctoral dissertation.

I have developed Loopae, an interactive software platform for computing, analyzing, and visualizing transportation network equilibria. I continue to refine and extend its capabilities.
