Nairobi, Kenya | Geospatial analytics | Climate and health
Geospatial evidencefor climate resilient health systems.
I use satellite imagery, GIS, spatial epidemiology, digital research data systems and reproducible Python workflows to map climate sensitive health risks. My work connects heat, flooding, WASH, settlement change, health facility access, population vulnerability and field surveillance systems. I translate complex spatial and survey data into clear maps, datasets, manuscripts and decision products for research, implementation and policy teams.
Research identity
Health systems researcher with a geospatial spine.
My work sits at the intersection of climate science, environmental exposure assessment, population health and implementation evidence. I build reproducible workflows that move from raw satellite and surveillance data to publication ready outputs, technical reports, dashboards and decision products.
Current work focuses on climate and health analytics in East Africa, including extreme heat, flood exposure, WASH resilience, peri urban transition, health service accessibility, surveillance data systems and operational decision support.
Clear questions, defensible methods and outputs aligned to publication and implementation needs.
Python, Earth Engine and GIS workflows that are documented, reproducible and ready to hand over.
Maps, figures, narratives and dashboards that make complex analysis understandable to decision makers.
