Research Interests:​​

  1. Resilience of Urban Coupled Socio-Physical Systems

    • Inferring the inter-dependencies between urban social and physical systems, and how they affect the resilience of cities.

    • Prescriptive modeling to guide policies for resilient and sustainable urban growth.

  2. Location Big Data Analytics for Disaster Response

    • Analysis of population displacement and recovery after shocks (e.g. disasters, pandemics) using mobile phone location data, social media data, and satellite imagery.

    • Causal impact estimation of shocks on business performances using mobility data.

  3. Artificial Intelligence for Urban Science

    • Deep learning-based methods to understand urban functionality, hierarchical structures, and similarities between cities using dynamic trajectory data.
