Departmental Research Seminars Series

Integrating geospatial data to measure mobility changes and pathogen transmission risks

Date: 20 DEC 2023 (Wednesday)

Time: 10:00 - 11:30 (HKT)

Venue: CLL, Department of Geography, 10F, The Jockey Club Tower, Centennial Campus, HKU



Dr Shengjie Lai will provide an overview of work using a wide range of geospatial and epidemiological datasets and models to: a) Measure changes in human mobility across space and over time; b) Evaluate the risk of infectious diseases such as COVID-19 and dengue spreading through travel networks; c) Assess the effectiveness of different public health interventions in mitigating transmission.

Dr Shengjie LAI

Principal Research Fellow (Full-time Permanent), University of Southampton, UK

Dr Shengjie Lai is a Principal Research Fellow (Full-time Permanent) at the University of Southampton, UK. He is currently leading the Dynamics and Mobility (DM)/Spatial Epidemiology and Public Health (SEPH) group within WorldPop ( Dr Lai is also a Fellow of the Royal Society of Public Health (FRSPH) and a Fellow of the Royal Geographical Society (FRGS) in the UK. Funded by national and international funders, he is interested in the interactions between human mobility, environmental changes and infectious disease dynamics. His research has led to pioneering approaches to the use and integration of multidisciplinary approaches, e.g. GIS and epidemiology, and novel data sources such as mobile phone and Internet check-in data, to measure changes in mobility patterns, pathogen transmission risks and intervention effects. He has published >150 papers in scientific journals such as Nature, Science, Lancet Infectious Diseases, Nature Medicine, BMJ, Nature Human Behaviour, and Nature Communications. These studies have had strong policy implications for disease outbreak responses and have been featured in global media outlets such as BBC.
