Topic description
This PhD project aims to characterize the evolutionary dynamics of sarbecoviruses and their virus-host
interfaces, building on a longitudinal study spanning over a decade in colonies of Rhinolophus
ferrumequinum bats, as well as experimental, omics, and analytical approaches developed for this study.
By combining genomic and phylogenetic analyses, functional studies targeting innate and adaptive
immune responses, and controlled experiments on virus-cell interactions, the PhD candidate will explore
the mechanisms enabling certain sarbecoviruses to cross species barriers and evolve toward zoonotic-
risk phenotypes. The project is designed in direct continuity with work conducted under the EU MuseCoV
and ANR EmerCoV projects, and closely integrated with a postdoctoral contract dedicated to screening
and functional characterization of bat sarbecoviruses. Ultimately, this integrative approach should
identify evolutionary signatures, to investigate their periodicity and virus-host determinants predictive
of interspecies coronavirus transmission risk.
Ce projet de thèse vise à caractériser la dynamique évolutive des Sarbecovirus et les liens avec leurs
interfaces virus–hôte, en s’appuyant sur une étude longitudinale de plus d’une décennie menée dans
des colonies de chauves-souris Rhinolophus ferrumequinum ainsi que sur des approches expérimentales,
omiques et analytiques développées pour cette étude. En combinant analyses génomiques et
phylogénétiques, études fonctionnelles ciblant les réponses immunitaires innées et adaptatives, et
expériences des interactions virus / cellule en conditions contrôlées, le doctorant explorera les
mécanismes permettant à certains Sarbecovirus de franchir les barrières d’espèce et d’évoluer vers des
phénotypes à risque zoonotique. Le projet est conçu en continuité directe avec les travaux menés dans
le cadre des projets EU MuseCoV et ANR EmerCoV et en articulation étroite avec un contrat post-
doctoral consacré au crible et à la caractérisation fonctionnelle de Sarbecovirus de chauves-souris. À
terme, cette approche intégrative doit permettre d’identifier des signatures évolutives, de tester leur
périodicité et de préciser les déterminants virus / hôtes prédictifs du risque de transmission inter-
espèces des coronavirus.

NAISSANCE DE L’UNITÉ INSERM DYNAMICURE – UNE RECONNAISSANCE DE L’EXPERTISE NORMANDE SUR LES MALADIES INFECTIEUSES
Du fait de son expertise et de ses recherches sur les pathogènes et les maladies infectieuses, le Groupe de Recherche sur l’Adaptation Microbienne (GRAM 2.0) a obtenu la labellisation Inserm avec création de l’Unité Mixte de Recherche UMR 1311 DYNAMICURE pour « Dynamique Microbienne associée aux Infections Urinaires et Respiratoires ». Cette reconnaissance est le fruit du regroupement de chercheurs hospitalo-universitaires des CHU de Rouen et de Caen et d’enseignants-chercheurs des universités de Caen et Rouen Normandie, et d’un recentrage sur ces deux thématiques, qui représentent un enjeu majeur de santé publique...

Candidate's profile
Candidate profile - Applicants must hold a Master 2 in virology, biological sciences, or a related discipline, with preferred proven expertise in virology, microbiology, molecular biology, ecology, or biochemistry.
Proficiency in at least one of the following areas is required:
- Work in BSL-3 or BSL-2+ facilities
- Molecular biology (PCR, RT-qPCR, cloning, mutagenesis, silencing, NGS library prep, etc.)
- Cell culture (2D lines, explants, organoids)
- Next-generation sequencing (metatranscriptomics, single-cell RNA sequencing, etc.)
- Virology (isolation, cultivation, TCID50, transfection)
- Immunology (serology, ELISA, PBMC isolation/stimulation, sequencing)
- Cell biology / Proteomics (protein production / purification / in cell P-P interaction, western blot, etc.)
Preferred additional skills: viral genomics, NGS/bioinformatics, phylogenetic analysis, and scripting (Bash, R, Python). Excellent English proficiency is required; French skills are an advantage. The role demands strong teamwork, communication, and collaborative spirit.
