  • Urban Mobility
  • Millions of people are moving in the city every day. What are the patterns of these movements? What are the connections of these movements and urban built environments? In what extent could we control urban mobility by adjusting the urban settings? I'm thrilled about exploring these fundamental problems in urban science. Billions of call details record data, traffic survey data together with built environment data are jointly analysed to find answers to these problems.

  • Real Estates
  • More and more real estate developers invest not only on real estate but also on supporting facilities, such as hospitals and schools, to improve their property value. I developed an interpretable Bayesian model to evaluate the impact of built environments on housing price to support real estate developers and urban planners making expensive decisions. Submarket effect is especially treated, which represents the overall effect of heterogeneity in real estates market.

  • Epidemiology
  • In response to the outbreak of COVID-19, my colleagues and I developed a spatio-temporal model to simulate the trend of COVID-19 based on ordinary differential equations. The huge domestic migration during the spring festival of China is featured in the model. Simulation is performed to answer the questions: "When will the inflection point come?", "Are traffic blockage and quarantine effective in terms of prevention?", "What if the quarantine is launched earlier or later?" etc.

  • Urban Data Management
  • Urban data is of various kinds and comes from both enterprises and government. One of the challenges in urban data management is to protect data assets when urban applications require data sharing from a variety of enterprises and government agencies. We developed a data sharing model based on blockchain technology enabling protecting data assets while sharing data.
