Peter Macharia
Postdoc in spatial epidemiology
Peter Macharia develops geostatistical methods to map disease prevalence in presence of incomplete spatial information using school survey data. He works closely with Professor Bob Snow and Dr Emelda Okiro
Peter is interested in spatial health metrics to aid in a better understanding of health inequalities, vulnerabilities, and population health through the use of conditional autoregressive and geostatistical models. He also maps physical access, marginalization, and vulnerability indices.
