After a PhD in Biology in 2011 on population genetics and phylogeography on amazing little amphipods (Crangonyx, Crymostygius) at the University of Reykjavik (Iceland), I pursued my interest in Bioinformatics and Evolutionary Biology in various post-docs in Spain (MNCN Madrid, UB Barcelona). During this time, I investigated transcriptomic landscapes for various non-model species (groups Conus, Junco and Caecilians) using de novo assemblies and participated in the development of TRUFA, a web platform for de novo RNA-seq analysis. In July 2016, I integrated the Revive Consortium and the Epigenetic Regulation unit at Pasteur Institute, where my main focus were transcriptomic and epigenetic analyses on various thematics using short and long reads technologies, with a special interest in alternative splicing events detection. I joined the Bioinformatics and Biostatistics Hub in January 2018. My latest interests are long reads technologies, alternative splicing and achieving reproducibility in Bioinformatics using workflow managers, container technologies and literate programming.

Transcriptomics of Anopheles – Plasmodium vivax interactions towards identification of malaria transmission blocking targets
Despite the worldwide importance of malaria due to Plasmodium vivax, there is currently almost no data on the molecular responses of the Anopheles mosquito vectors to this parasite species. Understanding these responses will contribute to identify relevant strategies to interrupt the transmission of P. vivax by targeting the mosquito vector. Such approaches are urgently needed, as P. vivax is difficult to target on the long term in humans as a consequence of the hypnozoite stage that is responsible for relapses. This project will investigate the molecular response of Anopheles arabiensis, member of the Anopheles gambiae complex, to P. vivax from experimental infections performed in Madagascar where both mosquito and parasite are present. This is a unique situation that will capitalize on the strong knowledge and tools available for An. gambiae sensu lato. The response will be compared to the one triggered by P. falciparum, also present in Madagascar. From mosquitoes infected in a field setting, a transcriptomic (RNAseq) approach will be used to identify common and unique pathways to both parasite species. These analyses will further contribute to identify targets for interrupting transmission of each or both parasites simultaneously. However, a pilot study performed with the PF transcriptomics & epigenomics revealed that the current release of the An. arabiensis genome is poorly annotated. Therefore, to be able to make sens of the RNAseq analyses per se, a strong support from the C3BI Hub for bioinformatics and biostatistics is critical.
Cepia mass produces two species of Anopheles mosquitoes for research teams studying malaria. The aim of this project is to assess 1) whether or not the compostion of the bacterial microbiota fluctuates over time and if so to what extent ; 2) if there are significant variations can these be correlated with the degree of infectability by plasmodium parasites and/or the fitness of the mosquitoes (measured by their survival rate).
The mechanisms underlying Anopheles mosquito susceptibility to malaria parasite infection in nature are not understood. We infected wild Anopheles pedigrees in West Africa to map loci for susceptibility to the human malaria parasite Plasmodium falciparum. Individuals from phenotyped pedigrees were entirely sequenced in order to identify and fine-map segregating loci.
The highest global malaria prevalence is in Africa, where the most important vectors are members of the Anopheles gambiae species complex. We generated a large curated panel of infected wild Anopheles gambiae mosquitoes in West Africa to analyze for association of genetic variants with susceptibility to the human malaria parasite Plasmodium falciparum.
Enhancers are cis-regulatory elements that control developmental and spatial gene expression in eukaryotes. Enhancers have been little studied in mosquitoes, including the Anopheles vectors of malaria.
To better understand the vector specificity of Aedes aegypti mosquito in the transmission of the alphaviruses CHIKV and ONNV, we are using an in vitro system to specifically depict critical viral infection steps at the molecular level: transcription and replication of the viral genome. This in vitro system requires mosquito cell transfections followed by luciferase quantification. For better describe the viral replication in mosquito cells, we need to characterize our mosquito cell lines since it is well established that some insect specific viruses (ISVs) modulate arbovirus infection in vectors. In order to determine whether our mosquito cell lines are infected by ISVs , we have already sequenced respectively total and small RNAs of our cell lines: Aedes aegypti Aag2 cells and Anopheles cells ( 4A3a, 4A3a and SUA4). The analysis of these data will furnish global and comprehensive cell features regarding the presence of ISVs which may interfere with viral infections in mosquitoes.
