studies focus on the biochemistry, molecular biology and immunology of antigens
expressed in the sexual stages of malaria parasite and host-parasite
interaction. Some of the major projects currently include: (i) molecular
mechanisms of sexual differentiation in Plasmodium,
(ii) development of a malaria transmission blocking vaccine, (iii)
characterization of malarial 'recombinosome', (iv) immune- and molecular
epidemiology of malaria studies in Zimbabwe and Zambia, (v) malaria and
helminth co-infections in mouse models and in humans, (vi) sporozoite –
salivary gland interactions, (vii) determinants of malaria transmission
success, (viii) K+ channels and malaria transmission, (ix) malaria specific
memory B cell responses, (x) development of transgenic murine malaria parasites
as tools to investigate transmission blocking vaccines.
