I am a geospatial analyst, a Commonwealth PhD scholar and an associate fellow of the Royal Geographical Society (with Institute of British Geographers). My work and that of my supervisors is transformative and broadly focuses on advanced spatial analysis in environmental and health applications, and in the intersection of these research areas. This includes the application of remote sensing and predictive environmental modelling to understand vector-borne diseases transmission risk in a changing climate.
My particular focus is on elucidating the underlying mechanisms linking climate change and snail-schistosome distribution using satellite and drone images to help improve capacity for prevention, preparedness and response to neglected tropical diseases and climate risks.
