I am interested in using numerical and analytical tools to understand complex systems in ecology, in particular relating to their spatial structure and interactions between species and the environment.
In this project, working with Giulia Vico and Samuli Launiainen, I am looking at different mangment practices of boreal forests affects their response to climate change. In particular, we are interested in how more frequency disturbances such as fires and pest outbreak, together with stress due to water shortage, impact primary production in forests and reliability of forests yield.

After studying Physics for my Bachelors and Masters, I moved to the Institutes for Desert Research (BGU), where I did my PhD, studying regime shifts and specifically desertification in dryland ecosystems. For my second postdoc I joined the CNRS station in Moulis, France, where my research focused on ecosystem stability, in particular focusing on the how spatial structure of the ecosystem and of disturbances affects its response to these disturbances, and thus its stability properties.

I then joined SLU to work with Riccardo Bommarco, looking at the effect of nutrient subsidies on food webs. Our goals was to understand how the subsidies trickle up and down the food web, potentially leading to a shift in the system's behavior, and how it relates to various functions of this system, such as the biomass productivity of the primary producers.
