Emulator-based Bayesian optimization for efficient multi-objective calibration of an individual-based model of malaria (Publications)
framework employing Gaussian process or machine learning emulator functions to calibrate a complex malaria transmission simulator. We demonstrate our approach by optimizing over a high-dimensional parameter [...] a portfolio of multiple fitting objectives built from datasets capturing the natural history of malaria transmission and disease progression. Our approach quickly outperforms previous calibrations, yielding
<em>Plasmodium falciparum</em> parasite prevalence in East Africa: updating data for malaria stratification (Publications)
Burden High Impact (HBHI) strategy for malaria encourages countries to use multiple sources of available data to define the sub-national vulnerabilities to malaria risk, including parasite prevalence. Here [...] to provide a more contemporary understanding of the sub-national malaria prevalence stratification across the sub-region for 2019. Malaria prevalence data from surveys undertaken between January 2010 and
Detection of asymptomatic malaria in Asian countries: a meta-analysis of diagnostic accuracy (Publications)
Background: Achieving malaria elimination requires the targeting of the human reservoir of infection, including those patients with asymptomatic infection. The objective was to synthesise evidence on the [...] accuracy of the rapid- onsite diagnostic tests (RDTs) and microscopy for the detection of asymptomatic malaria as part of the surveillance activities in Asian countries. Methods: This was a meta-analysis of [...] that evaluated the diagnostic per- formance of RDTs and microscopy for...
Multi-dose priming regimens of PfSPZ vaccine: safety and efficacy against controlled human malaria infection in Equatoguinean adults (Publications)
Tolerability, safety, immunogenicity, and vaccine efficacy (VE) against homologous-controlled human malaria infection (CHMI) 6-7 weeks after vaccination were assessed to down-select the best regimen. All four
The 3-phosphoinositide-dependent protein kinase 1 is an essential upstream activator of protein kinase A in malaria parasites (Publications)
t protein kinase A (PKA) signalling is essential for the proliferation of Plasmodium falciparum malaria blood stage parasites. The mechanisms regulating the activity of the catalytic subunit PfPKAc, however [...] function has not been investigated in gametocytes, the sexual blood stage forms that are essential for malaria transmission. By studying a conditional PfPKAc knockdown (cKD) mutant, we confirm the essential role

interventions. However, current recommendations focus exclusively on stratification by malaria risk. Yet, malaria is multi-factorial and the impact of interventions in a given setting also depends on [...] conceptual framework for a multi-dimensional malaria stratification beyond mere epidemiological indicators. Papua New Guinea (PNG) with its complex malaria epidemiology serves as a model country. Project [...] To improve the (cost-) effectiveness of malaria control and accelerate progress...
