Personal profile
Research expertise
I am a spatial epidemiologist / geospatial analyst
Interested in spatial health metrics for improved understanding of health disparities and inequalities, vulnerabilities, and population health at high spatial and temporal resolution in SSA and LMICs. Particularly geographic access to healthcare, population marginalisation and vulnerability indicators, coverage of interventions, disease prevalence and associated determinants. I have expertise working with a variety of datasets, but mostly household surveys, censuses, health facility data, environmental data, demographic and socioeconomic datasets. I used mapping (QGIS, ArcGIS) and statistical software ( R and STATA)
I've trained various audiences on how to apply spatial analysis and GIS in class, research, work and implementation settings especially for public, and global health. I have a PhD in spatial epidemiology, a Master's in GIS & remote sensing, a PgDip in Health Research, and a BSc in Geomatic Engineering & GIS. I am widely published in spatial epidemiology.
