University of Southampton

I am a PhD graduate at the WorldPop, University of Southampton. My research focuses on how environmental and policy changes shape human behaviours and population health, bridging geospatial data sciences, computational social science, econometrics, and public health.

My current work focuses on three themes: 1) Spatiotemporal population dynamics, mapping monthly, daily, to hourly population distribution by integrating mobile phone positioning and geospatial data. 2) Human behaviours and disease dynamics, drawing on social media and digital traces data to examine how human mobility and health behaviours shape infectious disease transmission, and how health interventions affect mental well-being. 3) Human mobility and climate change, which investigates the impacts of climate and environmental exposure, including floods, tropical cyclones, and wildfires, on human mobility and population health.

Interests

  • Causal relationships between population health and environmental exposure or health policy
  • Human-centred AI applications for behavioural modelling
  • Spatial, demographical, and individual heterogeneity in behaviours and health risks

How Multi-Hazard Early-Warning Systems Benefit Mobility Resilience to Tropical Cyclones

To what extent does multi-hazard early warning help resist extreme weather? What is the combined effect of multi-level warnings when facing tropical cyclones of varying intensities?

Connected and Contagious: How Social Connections, Mobility Networks, and Physical Contact Jointly Shape Infectious Disease Transmission

How physical and social connections jointly shape the spread of infectious disease? What knowledge can we learn from social scientists, network scientists, and epidemiologists? What are the promising strategies for an integrated disease modelling in the future?

Individuals’ Self-Disclosure on Social Media Reveals Sentiment and Mental Well-Being Benefits of Vaccination

What are the mental benefits of vaccination beyond its physical protection? How can we gain fast, large-scale evidence beyond traditional surveys? A quasi-experimental design on social media can provide an answer.

When geostatistics meets machine learning: how do they compete and complement in dynamic population mapping?

Can geostatistical models or machine learning better capture population dynamics? Which performs better under different data availability? How can their strengths be integrated for more precise dynamic population modelling?
