Research interests

Edson is primarily interested in developing novel spatial and spatiotemporal statistical methodology and applying these to solving real-world problems. His current research focuses on mapping childhood vaccination coverage in low- and middle-income countries. He has ongoing collaborations with global health organisations that involve work related to vaccination coverage estimation - both nationally and globally - and mapping other health and development indicators. Edson also has interests in time series analysis, Bayesian modelling and computation and general statistical methodology.

Nigeria VaxPop project – focuses on geospatial analysis of data on vaccination coverage, mostly from multi-indicator household surveys and post-campaign coverage surveys to support the country’s vaccination program. This project is funded by the Bill & Melinda Gates Foundation.

Novel Bayesian time series regression methods for estimating national immunization coverage - aims to develop a new methodology for estimating immunization coverage for multiple vaccines and all WHO countries as an alternative to WUENIC estimates. This project is funded by WHO.

Mapping under-/un-vaccination populations in low- and middle-income countries -  focuses on estimating populations living in remote-rural areas, conflict areas, urban slums and refugee camps, and analysis of their characteristics. This project is funded by GAVI  and Bill & Melinda Gates Foundation.
