Chris  joined the WorldPop team in 2016 to contribute to poverty mapping and spatial demographic analyses. He left as a full time member of the team in 2022, but continues to work with us as a visitor. 

His research focuses on developing and applying quantitative spatial methods to explore the geographic patterns of human health and disease, particularly how social, economic, and political contexts shape human-environment interactions. He received his PhD in Geography from the University of Colorado Boulder (USA), studying the social and spatial patterns of exposure to arsenic-contaminated drinking water and resulting health impacts in rural Bangladesh. Previously he worked with the Geographic Information Science and Technology group at Oak Ridge National Laboratory on high spatial/temporal resolution population distribution models.
