The Impact of Antimalarial Resistance on the Genetic Structure of Plasmodium falciparum in the DRC

This study examines the impact of antimalarial resistance on the genetic structure of Plasmodium falciparum populations in the Democratic Republic of the Congo. Using population genetic approaches, we demonstrate how drug resistance shapes parasite …

Under the Radar: Epidemiology of Plasmodium ovale infections in the Democratic Republic of the Congo

This study examines the often-overlooked epidemiology of Plasmodium ovale infections in the Democratic Republic of the Congo. P. ovale has received limited attention compared to P. falciparum and P. vivax, yet understanding its distribution and …

The Epidemiology of Asymptomatic P. vivax Among Adults in the Democratic Republic of the Congoo

Presentation of the first aim of my PhD dissertation, which focused on the epidemiology of P. vivax in the Democratic Republic of the Congo, at the annual American Society of Tropical Medicine and Hygiene conference. This work is now published in Nature Communications1.

Pooled Deep Sequencing of Drug Resistance Loci from Plasmodium falciparum Parasites across Ethiopia

Although Ethiopia has an overall lower prevalence of Plasmodium falciparum among countries in Africa, the emergence of drug resistance could seriously hinder elimination efforts. Using samples collected from five therapeutic efficacy studies …

Prevalence of Molecular Markers of Antimalarial Drug Resistance across Altitudinal Transmission Zones in Highland Western Uganda

We explored spatial variation in the prevalence of established molecular markers of antimalarial resistance across a geographically diverse, highland region of western Uganda. We identified Plasmodium falciparum CQ resistance transporter 76T …

The changing landscape of Plasmodium falciparum drug resistance in the Democratic Republic of Congo

BACKGROUND: Drug resistant malaria is a growing concern in the Democratic Republic of the Congo (DRC), where previous studies indicate that parasites resistant to sulfadoxine/pyrimethamine or chloroquine are spatially clustered. This study explores …

Plasmodium vivax chloroquine resistance links to pvcrt transcription in a genetic cross

Mainstay treatment for Plasmodium vivax malaria has long relied on chloroquine (CQ) against blood-stage parasites plus primaquine against dormant liver-stage forms (hypnozoites), however drug resistance confronts this regimen and threatens malaria …

Plasmodium vivax Infections in Duffy-Negative Individuals in the Democratic Republic of the Congo

Although Plasmodium vivax has been assumed to be absent from sub-Saharan Africa because of the protective mutation conferring the Duffy-negative phenotype, recent evidence has suggested that P. vivax cases are prevalent in these regions. We selected …

polyIBD: Inferring Identity by Descent in Complex, Polyclonal Infections

Presentation at the annual Genomic Epidemiology of Malaria conference presenting early work on polyIBD a hidden Markov model for inferring identity by descent in polyclonal infections using a Bayesian framework. This project is currently in preparation.

Whole Genome Analysis of Polyclonal Plasmodium vivax Relapses in Cambodia

Oral presentation at the annual American Society of Tropical Medicine and Hygiene conference analyzing the genomics of P. vivax relapses from Cambodia.
