Two PhD positions to work on Disease Modelling
Two (2) PhD positions to work on developing an integrated model for the spread of Plasmodium transmission blocking symbionts and effects on malaria incidence at the International Centre of Insect Physiology and Ecology (icipe), Kenya
The two PhD studies are part of the project “to explore key characteristics of the mosquito symbiont Microsporidia MB, to determine whether it has the potential to be developed as a malaria control intervention” granted to the International Centre of Insect Physiology Ecology (icipe) and funded by the Bill and Melinda Gates Foundation (BMGF).
Malaria is a human disease caused by a protozoan parasite vectored by mosquitoes of the genus Anopheles. The malaria disease burden remains a major impediment to good health and economic development in many regions of sub-Saharan Africa (SSA). In 2018, a total of 228 million cases were reported that resulted in 405,000 deaths, a strong indication that current control measures and their deployment levels are insufficient. Large-scale insecticide-treated net (ITN) distribution campaigns have had a significant impact on reducing the number of malaria cases. However, many malaria vectors have now evolved resistance to the insecticides used in ITNs and they are increasingly biting in outdoor conditions, where nets offer no protection. These factors threaten to reverse the gains achieved for malaria reduction and indicate an urgent need for new strategies to control Anopheles mosquito populations or their capacity to transmit Plasmodium parasites.
One of the most promising new vector management strategies involves the use of vertically transmitted symbionts (from mother to offspring) that decrease the vectorial capacity of their hosts. These symbionts can be disseminated through insect populations. By virtue of their vertical transmission, they offer a more sustainable strategy for the control of vector-borne disease transmission than conventional methods. This strategy is currently used as a control mechanism against Dengue, through the bacterial symbiont Wolbachia. A similar control strategy could be transformative and sustainable for malaria control, but this will require research for development (R4D) efforts on Anopheles-associated microbes with transmission-blocking capacity.
We will use generic and flexible methods to illustrate the interactions and feedbacks with the integration of the hypothesis of the cause and effect of the Plasmodium transmission blocking symbionts on malaria incidence. Two modeling approaches will be used: (i) the Integrated system dynamics simulation model; and (ii) Individual-based modeling (IBM). These modeling strategies will formulate malaria transmission models that combine Anopheles vectors, Plasmodium parasites, humans, and the environment and with transmission-blocking symbionts and other factors such as insecticide resistance. Prior to the modeling experiments, we will establish the hierarchy process to elicit a ranking of the determinant of individual components of the vectors-parasites-human-environment system. This step will consist of identifying and visualizing the interactions among the determinants of each component of the system using the cause and effect principle and prioritize them by means of an analytics hierarchy process (AHP) and network analysis (NA). The cause-and-effect sketches will further, provide means to improve strategies for more and effective scrutiny of the determinants of the system components by scouting underestimated channels. The development of models specific to Microsporidia MB will involve iterative processes and integration with laboratory and field experiments. Modelling experiments will evaluate the applied potential of transmission-blocking symbionts in Anopheles and guide the development of optimal dissemination strategies. In addition, models specific to Microsporidia MB will predict how release programs could impact the overall malaria transmission landscape and how malaria case burden would be affected under different environmental conditions. The first PhD research will apply System dynamics (SD) and the second will use Individual (agent) based modeling (IBM).

Can I get a student loan for a doctorate UK?
You can apply for a loan if your doctoral program includes an integrated master’s degree (even if you already have a master’s degree). You must register for a full doctoral degree. You will not be able to apply for a separate Postgraduate Master’s Loan.
