During the course of my first undergraduate studies at the University of Edinburgh, (together with Jaap de Roode and Andrew Read) I have been interested in malaria. In particular interested in the study of different classes of parasite clones (Plasmodia) competing to feed on the host organism. This is a common scenario during an infection of malaria.
In repeated experiments with different classes of parasite invading the hosts, it was possible to show that stronger classes of parasite clones outcompete less virulent ones, thereby causing higher exploitation of food resource (blood anaemia and risk of death for the host).
This finding was published in PNAS (de Roode, Pansini et al., 2005).
