My research (in collaboration with Profs Tait and Turner) involves investigating the system of genetic exchange in African trypanosomes, which has recently been demonstrated to have a Mendelian system of inheritance (Mol. Biochem. Parasitol. 2005; 143; 12-19). It is thus possible to exploit this genetic system to adopt a linkage mapping approach to identifying genes that are involved in traits relevant to the transmission, virulence, host specificity (Parasitology; 2004;129;445-454) and treatment of the disease it causes, African sleeping sickness. To this end, the first genetic map of this parasite was constructed based on microsatellites (Nucleic Acids Res.2005; 33; 6688-6693), which, together with the publication of genome sequence, has opened up this field of study. The large array of microsatellite markers, which have been physically and genetically mapped have also been used to examine the population structure, the role of genetic exchange in the three different sub-species of the parasite and to examine the nature of virulence variants in natural populations (J. Infect. Dis.2007; 196; 1620-1628).
