“My interest in life sciences is probably based on
the fact that during my youth I lived close to nature. I discovered Ecology, as a science, during my masters thesis at the National Natural Park of Cevennes in the center of France. As a follow up, my PhD thesis was to understand the dynamics and behavior of viviparous lizard populations in this natural area. We conducted a demographic survey of these populations and a data analysis in order to understand the factors behind the variation in population densities and what can influence these processes. Ecology is a very challenging science given the large range of questions addressed and the varied approaches involved based not only on ecological, molecular and genetic tools but also statistical or numerical modeling.

 

My research is focused on the study of plant gene dispersal
in agro-ecosystems with oilseed rape as a crop species model. Oilseed rape is a particularly relevant as a plant model for studying the escape of cultivated species from fields because for the wild relatives of this species the risks could be particularly high. In general, the evaluation of benefits and risks associated with the cultivation of transgenic plants raises the problem of the inter-relationships between cultivated and wild plants and the impact of novel genes on the rest of biodiversity. Why favour an artificial structure associated with one or a handful of herbicides which may have negative consequences on biodiversity, whereas agriculture using biological control of ecosystems for regulation appears to be a more sustainable solution? It is then necessary to advance research that combines both agriculture and ecology.”
