In 2006, she passed the administrative assistant competition at INRA and was recruited in the IHPM unit at Oniris. In 2012, she obtained a BAC Pro in secretarial studies and joined the corps of research technicians. She coordinated and carried out research support activities in administrative, financial and human resources management (management of research contracts, management of the unit's budgets, support for the steering of the unit, personnel management) within the UMR BIOEPAR. She has now retired.
Bareille Servane - Master 2
Servane Bareille was hosted at BIOEPAR (DYNAMO), as an M2 intern for the MODE master's degree (modelling in ecology) in Rennes. She analysed the feedback from the international teams involved in the ASF-Challenge, which is coming to an end. These teams have been trying for several months to predict the outcome of an epidemic ... of African swine fever and to evaluate the relevance of control actions. It has identified the most promising modelling methods used by the teams to guide public decision making according to the questions addressed.
Berquier Florian - Master 2
Florian Berquier (M2 from Rennes) joined the TIBODI team. He worked on the development of the amplification of genes used as markers of genetic diversity in piroplasmas responsible for equine piroplasmosis. He was with us until 28 May 2021.
We welcomed Anaïs Bourriau from 10 May to 25 June 2021 in the TIBODI team as a BTS intern. The subject of her internship was the analysis of the transmission of Theileria equi by ticks.
Caroline Constancis, a graduate of Agrocampus Ouest, was welcomed by BIOEPAR as a university doctoral student. She was supervised by Christophe Chartier, Nadine Ravinet and Florence Hellec (sociologist in the Aster unit (INRA SAD) in Mirecourt) to work on the technical and sanitary advantages of the new methods of managing dairy calves under a nurse in organic farming (from the point of view of the farmers to the quantification of the effects on health). In addition to describing these innovative practices, which are currently poorly documented, Caroline assessed the impact on calf health and analysed the innovation strategy of farmers who have chosen to work in this way to raise their calves.
To obtain her engineering degree in bioinformatics and modelling at the Institut National des Sciences Appliquées (INSA) in Lyon, Hélène carried out her end-of-study internship in Bristol, UK, at the Bristol Robotics Laboratory, during which she worked on the development of an agent-based model simulating the propagation of nanoparticles in a brain tumour. This model was tested on a swarm of 1000 robots (Kilobots) that she had also helped to build during her internship.
After this international experience, Hélène joined the Bioepar team as a modelling engineer. She worked on a spatio-temporal model of tsetse fly population dynamics (Cecilia et al. 2019) based on data from the eradication campaign conducted in Senegal by CIRAD, a project partner. This model should enable the development of effective control strategies against this vector species.
After a sabbatical year partly spent travelling the roads of South-East Asia, Hélène returned to Bioepar to start her PhD in October 2018. She worked on the development of a model capable of understanding and predicting the spread and persistence of Rift Valley fever in West Africa as part of the FORESEE project. She was co-supervised by Pauline Ezanno (Bioepar), Raphaëlle Métras (INSERM, IPLESP, UMRS-1136) and Renaud Lancelot (CIRAD, UMR Astre).
He was welcomed at BioEPAR within the TiBoDi group as a PhD student. His subject was entitled "Role of Midichloria mitochondrii, an endosymbiotic bacterium of the tick Ixodes ricinus, in the physiology of its host". He was supervised by Olivier Plantard and Davide Sassera from the University of Pavia (Italy), where he did his second year of thesis.
Camille Deflesselle (ESIEE Paris) joined the DYNAMO team from 19 April to 6 August 2021. She worked on the development of graphical representations of models and simulation outputs in highly structured breeding systems, in support of Vianney Sicard's thesis.
Pauline Ferrand did her internship in the TIBODI team from 1 March to 16 July 2021. She prepared a professional licence and her subject is part of the PiroGoTick project: molecular detection and visualisation of T. equi in tick organs.
We welcomed Coralie Fuertes for an internship on colistin resistance until the end of July. Her subject was the implementation and study of the contribution of an ontology integrating data relating to diseases of farmed monogastric animals.
Niki HAYATGHEIB, a veterinary doctor, joined BioEPAR within the APPIFISH group as a PhD student. Her thesis topic was the evaluation of the efficacy and safety of alternatives to antibiotics in the fish farming sector: towards a reduction in the development and spread of antibiotic-resistant bacteria in fish, in their environment and in fish farmers? It was supervised by Hervé Pouliquen, Didier Lepelletier (MiHAR Unit, Nantes University Hospital) and Emmanuelle Moreau.
The objectives of the thesis were:
- to evaluate the efficacy and safety of an alternative product against Aeromonas salmonicida sub salmonicida (Ass) furunculosis in rainbow trout under controlled infection and rearing conditions.
- to study the risk of diffusion of antibiotic-resistant bacteria and resistance genes from fish and their environment (water, biofilm, sediment) to fish farmers.
Nicolas Helsens joined BIOEPAR and SECALIM. His thesis topic was "Characterisation of bacterial communities and antibiotic resistance genes in farmed fish", as part of the Foodresistome project (RFI). He was supervised by Catherine Magras (SECALIM thesis director), Ségolène Calvez (BIOEPAR) and Hervé Prévost (SECALIM).
Maïwenn Joary (Master 1 Cartography and Environmental Management, Biology and Ecology course at the UFR of Nantes) carried out her internship from 3 May to 9 July 2021 in the TIBODI team on the "Development of an experimental device for measuring the activity of ticks (Ixodes ricinus) under controlled conditions using ethoscopes".
Stéphanie Larramendy (who has a dual training as an agricultural engineer and a doctor) is already working as a University Senior Registrar in the Department of General Medicine at the Faculty of Nantes, and as a general practitioner in private practice. She conducted her thesis work (Territorial and collective determinants of community infections with ESBL bacteria) in parallel with her other activities.
Study engineer. Research topics: Parasitology of cattle (including Gastro-Intestinal Strongyles and Ticks), Immunology, Serology, Coprology, Molecular Biology.
His thesis project aimed to develop output-based analysis methods for animal health surveillance based on the BVD study. This thesis project was integrated into the European project (STOC FREE) funded by the European Food Safety Authority (EFSA). The objective of the project was to develop a standardised tool for epidemiological surveillance of bovine diseases, estimating probabilities of freedom from infection from data of varying nature and origin. The development of the tool was based on data collected in Europe for the control of bovine viral diarrhoea. These data can be very diverse: results of biological tests looking for antigens, antibodies, etc. carried out on serum, milk, etc. on an animal or a group of animals, risk factors linked to the management of the farm. Various statistical methods were compared on the basis of their ability to predict a probability of infection. The model selected allowed studies at different levels of aggregation: individual, herd, region. It should also be adaptable to the surveillance of other diseases. It was supervised by : Aurélien Madouasse, Christine Fourichon.
Hannah Morel (M2) worked on new support strategies for farmers based on participatory meetings in the framework of the UniFilAnim Santé IAP.
After a PhD at the Institut Sophia Agrobiotech (UMR INRA 1355, CNRS 7254, UNS) defended in 2015 and a postdoctoral stay at the Earth and Life Institute (Université Catholique de Louvain) thanks to a "Move-In-Louvain" fellowship (co-funded by the Marie Curie Actions), Thibaut came to work at Oniris in the BIOEPAR unit from October 2018. His research topics concern spatial dynamics at different scales, applied to population biology or epidemiology. His thesis work helped to better understand how the spatial structure of the introduction area modifies the success of invasive species introductions, using stochastic numerical simulations and microcosm experiments. Using similar methods during his first postdoc, he also studied the interaction between the behaviour of individuals and the spatial structure of metapopulations, as well as their impact on their resilience after a disturbance. At Oniris, he worked within the Sant'Innov project to study methods for reallocating the movements of young beef cattle when they are transferred to fattening farms, in order to reduce epidemiological risks.
