The malaria parasite infects more than half a billion people each year, leading to close to a million deaths across sub-Saharan Africa, South East Asia and South America. Mutations in the parasite genome are central to the sustained disease burden associated with malaria. Drug resistance mutations have occurred rapidly, limiting the use of the cheapest and most readily available treatments. There are multiple highly polymorphic gene families in the parasite genome, which slows the host’s acquisition of natural immunity against infection and limits the efficacy of tested vaccines.

I joined Texas Biomed in May 2010 to work with Tim Anderson, Ph.D., in the Infectious Disease Research Laboratory, to explore the genetics of the most virulent of the human malaria parasites, Plasmodium falciparum. I will be combining microarray technology, ‘next generation’ sequencing and in vitro parasite culture to measure the mutation rate in the parasite genome. A better understanding of the mutational process in the malaria parasite is key to tackling public health aspects of malaria infection, notably the emergence of drug resistance and the development of efficacious vaccines.
