About Me

I am a Ph.D. supervisor and Tenure-Track Assistant Professor at the Department of Urban Planning, Tsinghua University (THU). Before that, I was a Postdoc Associate at SMART Centre, MIT under the supervision of Prof. Zhao Jinhua. I obtained my Ph.D. degree from The University of Hong Kong (HKU), supervised by Prof. Zhao Zhan. I was also a visiting PhD student at MIT Senseable City Lab, supervised by Prof. Carlo Ratti and Prof. Paolo Santi. I received my bachelor and master degrees from Tsinghua University.

I am always seeking highly motivated students to work with. Interested candidates are strongly encouraged to contact me via email, along with their resume. For those interested in PhD/Master positions in Fall 2027, early contact and potential collaboration experience is strongly encouraged to help us know each other.

My research interest lies in the intersection of Artificial Intelligence, Human Mobility and Urban Planning:

• Spatiotemporal Intelligence for Human Mobility Modeling: Developing spatiotemporal deep learning algorithms to model and predict human mobility in complex transportation systems. My previous work includes multimodal travel demand prediction, simulating potential demand distributions in newly planned transport networks, and analyzing irregular mobility patterns during special events.
• Artificial Intelligence for Urban and Transport Planning: Applying advanced AI methods—such as generative AI and deep reinforcement learning—to inform and optimize urban and transport planning decisions. Recent projects include designing transit-oriented development strategies through reinforcement learning and enabling human-in-the-loop urban design through diffusion-based generative models.
• Big Data and Travel Behavior Analysis: Leveraging large-scale urban data alongside statistical and machine learning techniques to understand individual travel decisions and their relationship with the built environment, enabling data-driven planning and policy evaluation. Recent studies include analyzing post-pandemic travel behavior patterns and exploring activity planning heterogeneity across different social groups.
