Research: Gary's main research focus is in the development of approaches for geographical targeting of scarce government and NGO resources across the planet but particularly in low and middle income countries. Gary’s research supports the UN’s call for a data revolution in support of the Sustainable Development Goals (SDGs) to help monitoring progress and contribute to geographic targeting of scarce resources. The majority of projects Gary has worked on recently have been co-designed with UN agencies and they are directly dealing with gaps in knowledge and providing required outputs for practitioners as well as furthering scientific knowledge.

Gary specialises in developing proxy metrics for measuring poverty using multi-source non-traditional data such as very-high spatial resolution satellite imagery (<1m) and open street map data. Gary is particularly interested in developing methods for using satellite imagery to map and monitor aspects of human livelihoods and how this could be used to support the targeting of resources to areas that are in specific need. 

Current research projects as principal or co-investigator: (1) Improving prediction of trends in prevalence of child wasting at country level: Exploring the impact of survey timing; (2) Mapping gender related barriers for immunisation using Geographic Information Systems (GIS); (3) Developing a childrens climate risk index with UNICEF.
