Christopher is a Research Associate within the Vaccine Epidemiology Research Group (VERG) in the Department of Infectious Disease Epidemiology. His background is in geographical and environmental sciences with a specialism in geographic information science (GIS). 

As a health geographer, his research primarily focuses on the application of GIS-based spatial analysis and geostatistical modelling in epidemiological research. Christopher's current research focus involves developing remote and field based techniques for the environmental surveillance (ES) of pathogenic organisms, with a particular focus on detection of S. Typhi in low-income settings. In addition he also has research interest in the environmental monitoring of SARS-CoV-2 and Aspergillus fumigatus.

Christopher completed his PhD at the University of Glasgow where he investigated the spatio-temporal distribution of human and animal leptospirosis in Northern Tanzania under the supervision of Prof Sarah Cleaveland and Dr Jo Halliday. He also obtained a BSc in Environmental Hazards from the University of Brighton and an MSc in Geographic Information Science and Remote Sensing from the University of Manchester.
