Curriculum Vitae

Modelling the food web of the Seine Estuary (Tecchio et al 2015).
Le Havre harbor by Claude Monet.

Research topics

Characterization and modelling of food-web functioning properties in coastal ecosystems:

- Inter-ecosystem comparisons of functioning and resilience properties
- Ecosystem health indicator development, based on food-web functioning
- Climate Change effects and cumulative impacts
- Overlooked microbial processes in the food-web functioning, e.g. parasitism of the phytoplankton

Methodological development of the used numerical tools (Linear Inverse Modelling – Monte Carlo Markov Chain, Ecological Network Analysis), with a special interest in quantifying uncertainty.

Social-ecological systems modelling with oriented di-graphs (qualitative modeling) and Bayeian Belief Networks, with an interest in indirect effects, between human actors, cascading through the food web. Crossed mathematical analysis of the indices used in ENA (Ecological Network Analysis) and SNA (Social Network Analysis). Application to questions linking Climate Change and Offshore Wind Farms. Special interest on the use of outputs from food web models in helping decision in coastal and estuarine management.
