I started in october 2017 a PhD project about the potential of the joint use of landscape graphs and genetic graphs to analyse the ecological connectivity of habitat.

2013 - 2017: Student engineer at AgroParisTech (Paris Institute of Technology for Life, Food and Environmental Sciences) with a major in Management of Natural Areas in Nancy (ex-ENGREF)

2015: Erasmus exchange at Wageningen University (Netherlands). Courses from masters of Environmental sciences and Forest and Nature Conservation

2011 - 2013: Two-year preparation (equivalent to a NHD in biology) for the highly selective French agronomy engineering schools entrance (Admitted to AgroParisTech) at the University of Bordeaux (Cycle Préparatoire de Bordeaux, CPBx)

2017: Student Assistant Research at INRA (French Institute for Agricultural Research, UMR Biodiversité, Agroécologie et Aménagement du Paysage) in Rennes with S. Aviron, A. Alignier and J. Baudry: Statistical analysis of the effect of landscape and agricultural practices evolution on the pluriannual dynamics of carabid species assemblages in the Zone Atelier Armorique (Long Term Ecological Research, Ille et Vilaine, France)

2016: Assistant Environmental Engineer in the Asociación de Ciencias Ambientales (Madrid, Spain): Analysis of the ecological connectivity in the Rio Henares watershed, gathering of information about water management and biodiversity, website management, as part of the "Proyecto Rio Henares"

2015: Assistant Park Ranger at Puyehue National Park (Lakes Region, Chile): Creation of the virtual herbarium of the park, patrols in the park, mapping, environmental education animations

2014: Assistant Environmental Engineer in the association ATHENA (Loir et Cher, France): Creation of a biodiversity indicator for the hedgerows network of the region Perche. Implementation on the field and presentation of the tool to the local stakeholders (Perche Regional Natural Park) 

The objective of my PhD project is to develop, experiment and compare methods of ecological connectivity modelling combining two graph-theoretic approaches: landscape graphs and genetic graphs. This coupling should allow to benefit from the advantages of both approaches. It could improve modelling methods used by biodiversity managers in order to take conservation measures.

This work draws upon landscape genetics studies, a field study at the interface between landscape ecology and population genetics.

The PhD project is funded by the ARP-Astrance company under a CIFRE contract. My supervisors are Jean-Christophe FOLTÊTE (UMR ThéMA, director), Stéphane GARNIER (UMR Biogéosciences, Dijon, co-director) and Hervé MOAL (ARP-Astrance, Paris, operational supervisor).
