Research
My research aims to understand how anthropogenic pressures alter ecosystems. The challenge in addressing this question is twofold. First, species respond in different ways to the same disturbance due to variability in their life-history traits. Second, species form complex networks, which make their dynamics intertwined and difficult to predict. I combine theoretical models and data analysis to address the following question: How do species interactions shape the effects of environmental pressures on ecological systems?
In particular, my current postdoctoral project focuses on quantifying the effects of dams and nutrient enrichment on food-web structure across France.
Expertises
My expertise lies at the interface between theoretical ecology, network science, and data-driven ecological analysis. I have a strong background in theoretical ecology, particularly in the development and analysis of dynamical models to study species interactions and their impact on species stability. This includes extensive experience with network theory and food-web ecology.
I am currently developing expertise in spatio-temporal Bayesian modeling, with an emphasis on accounting for spatial auto-correlation in stream networks.
I also have strong programming skills, with experience in R, Python, and Julia, which I use for to develop open-source libraries for the scientific community.
