This image is from a study investigating malaria in Papua New Guinea (PNG). Its rainbow-colored 'cosmos' of connected dots is loaded with valuable information about parasite populations and the spread of infection.
Each dot represents a malaria parasite that has been detected in blood samples collected from across the country. The colors of the dots denote the parasite's geographic origin. The red dots, for instance, show parasites that originated in the capital city of Port Moresby.
Abebe is using this technique to understand where infection hot spots are in PNG, how infections are spreading and what kind of control strategies are best employed on a path towards eliminating malaria.
