I am interested in the distribution and burden of inherited blood disorders. Despite a predicted increasing number of individuals affected both in high- and low-/middle-income countries, existing maps and population estimates for these disorders are mostly out of date. Using multidisciplinary skills acquired during my PhD (in forest entomology) and my post-doctoral experience, I apply contemporary mapping and modelling methods to contemporary collections of epidemiological data. Most of my work so far as focussed on haemoglobin S and C, but I am also involved in research on the Duffy blood group, G6PD deficiency and malaria. My research allows investigating both basic science questions, such as the spatial relationship between the distributions of the sickle cell gene and malaria, and applied science questions, such as the number of newborns affected by sickle cell disease at various scales.
Other aspects of my research that I would like to develop in the future include: the global cartography of other malaria selected disorders (typically, the thalassaemias and haemoglobin E) and of other medical conditions (e.g. phenylketonuria or diabetes) at sub-national level; the investigation of spatial and temporal changes in allele frequencies; the development of costs and mortality models for inherited blood disorders; or the spatial investigation of epistatic interactions between inherited blood disorders.
