My Background

13-16/02/2017

Context of current project:

• BVDV, economic endemic disease of cattle, a virus disease, wide spread throughout the world
• Understand BVDV spread mechanism at a regional scale, control and eradicate

Farming system at a regional scale (France):

• Herds are heterogeneous: demography, farmer decisions on control BVDV spread
• Herds are managed populations: highly structured (age groups)
• Direct / Indirect contacts through: animal trade / neighboring relations

Scientific interests:

• Develop a multiscale stochastic model, simulate BVDV spread at a regional scale (Bretagne)
• T

est collective control strategies, apply parameter estimation

• A tool for animal health organizations
• Generate theoretical models from simulation based model

Future interests: “data” related projects in applied areas
