I am mainly interested in theoretical ecology, specifically in the interspecific interactions on different trophic levels and their effects on community assembly. Lately this interest has been more focused in an agricultural context on pest-natural enemies systems. I did both my BSc (in ecology) and MSc (in evolutionary and fuctional ecology with a focus on theory and modelling) at Paris-Saclay university.
My PhD is entitled “Effects of eco-evolutionary dynamics on ecosystem services in heterogeneous agricultural landscapes – novel avenues for predicting biological pest control”.
Pesticide use has been proven to have negative effects on both the environment and human health. This has lead to increasing studies in alternative solutions to reduce crop damage from pest's attacks such as biological control through natural enemies (e.g. predators and parasitoids). Different theoretical and empirical frameworks have been used to better understand these pest - natural enemies systems, particularly focused in the meta-community framework. Nonetheless, even though this framework is useful to better understand this system’s community assembly it originally does not include evolution. As organism’s traits evolve they adapt to different pressures (biotic or abiotic), meaning that their response to their environment will not remain constant through time.
The aim of my PhD is to assess, through modelling, the effects that these eco-evolutionary dynamics (i.e. demographic and evolutionary dynamics) and agricultural landscape properties (i.e. landscape configuration and landscape composition) have on biological pest control. This will allow us to have a better understanding on the processes' that govern biological control and with this, be able to use this framework in the future to further develop biological control in practice.
