Peter Macharia is a PhD candidate of spatial epidemiology at The Open University UK, supported by the Initiative to Develop Research Leaders (IDeAL), based at the Kenya Medical Research Institute-Wellcome Trust Research Programme (KWTRP).  His PhD research focuses on modelling subnational child mortality, its determinants and their contribution since 1965 in Kenya. This work will allow benchmarking, inform policies, resource allocation and the realization of SDGs

Prior to this Peter was a geospatial modeller with the spatial health metrics group within KWTRP, where he worked on mapping populations at risk of malaria, coverage of malaria interventions, access to health services and developed spatial models to quantify bed-nets needed at each health facility in Kenya

He holds a MSc in Geospatial Information System (GIS)  and Remote Sensing from Jomo Kenyatta University of Agriculture and Technology(JKUAT), Postgraduate Diploma in Health research methods  from Pwani University and BSc in Geomatic Engineering and GIS from JKUAT

His interests are in disease mapping and spatial epidemiology (child mortality, its determinants, access and utilization to healthcare).

Peter is a member of The International Society of Geospatial Health , The GIS chapter of the Institution of Surveyors of Kenya and The American Association of Geographers
