My current research interests are focused on the blood stages of falciparum malaria. Our discovery that the invasion efficiency of falciparum parasites was markedly reduced by red cell dehydration (Blood,105:4853-4860, 2005) proved relevant to the understanding of the mechanisms by which inherited haemolytic anaemias with gene pools sustained in malaria-endemic regions, protect individuals against severe malaria.  In many of these anaemias, the presence of dehydrated, dense subpopulations of red cells in the circulation prevents the development of high parasitaemias, a pre-condition for disease severity. Our search for possible mechanisms of density-protection focused attention on an elusive pre-invasion stage of parasite-red cell interaction, during which falciparum merozoites align apically, ready to penetrate and infect red cells (Trends Parasitol. 23:481-48, 2007). This is the least understood stage of the invasion process. Elucidation of its mechanism may pave the way to novel malaria therapies. Investigation of the pre-invasion stage poses formidable technical challenges which we are currently trying to overcome in a multidisciplinary collaboration with colleagues from the Department of Physiology, Development and Neuroscience, the Cavendish Laboratory and the Wellcome Trust Sanger Institute (Biophys. J. 107:846-853, 2014).
