DYNAMO: Modelling in population dynamics and animal epidemiology

Understanding, anticipating and controlling the spread of animal diseases through mechanistic modelling: from intra-host mechanisms to epidemic dynamics at large scale, including decision and economic processes

DYNAMO aims to better understand and predict the spread and persistence of pathogens in animal populations, and to identify efficient and targeted control strategies. Such complex biological systems are studied at the within-host, between-host, and metapopulation scales, also using in the latter case trade network data and graph theory. We mainly focus on infectious diseases of cattle and swine, on arbovirus diseases, and on vector population dynamics.

Expertise & skills

  • Predictive modelling approaches combining mechanistic models and data-driven simulations
  • Model reproducibility, robustness, and clarity: a generic multiscale simulation framework to ease knowledge and data integration, and to capitalise developed models
  • Development of innovative inference methods to promote realistic models and quantify uncertain processes at different scales
  • Decision support tools for health advisers to guide on-farm management of livestock infectious risks and associated public health issues

On-going projects

  • WiLiMan-ID: Ecology of wildlife, livestock, human and infectious diseases in changing environments (2023-2028; funding: Horizon Europe)
  • DECIDE: Data-driven control and prioritisation of non-EU-regulated contagious animal diseases (especially respiratory and digestive diseases of young animals) (2021-2026; funding: H2020)
  • MIDIIVEC: Modelling and inference of intra-vector infection dynamics from experimental data (2022–2024; funding: INRAE MP Digit-BIO)
  • SEPTIME: Sensor-Enhanced Projection Tool Informed by an Epidemiological Model: a decision-support system based on the coupling between real-time sensor data and a mechanistic epidemiological model of bovine respiratory diseases (2022-2024; funding: Carnot Institute F2E)

Key past projects

  • RobustInfer: Combine & estimate: towards a reduction in data complexity to better calibrate large-scale dynamic epidemiological models (2021-2023; funding: région Pays-de-la-Loire)
  • ATOM: Automatisation of the software process from epidemiological models to decision support tools (2020-2021; funding: INRAE DPTI)
  • ASF Challenge: An interntaional modelling challenge to better predict the spread of african swine fever (ASF) at the wildlife / pig herd interface (2019-2021; funding: INRAE Animal Health Division)
  • FORESEE: Virus-host-environment interplay and drivers behind pathogen emergence, spread and persistence: Rift Valley fever (RVF) as a case study (2018-2021; funding: INRAE MP GISA)
  • CADENCE: Spread of epidemic processes on dynamical networks of animal movements with application to cattle in France (2017-2021; funding: ANR)
  • MIHMES: Multiscale modelling of infection dynamics, from intra-host to metapopulation scale, to evaluate control strategies (2012-2017; funding: PIA & FEDER Pays-de-la-Loire)
