Research interests

As part of the BIOSTASES team, my current goal is to contribute to the ongoing discussion on how to define stability in ecosystems from a theoretical standpoint, especially taking into account spatial and trophic dynamics. A distinctive aspect of this research is the choice to look at stability from the perspective of the ecosystem's functioning, rather than its detailed biological inventory. This means that stability is not taken to be a property of the community itself, but of specific processes within and beyond the ecoystem, including its interface with human society.

This project furthers my personal interest in function in complex systems in general, which I have been exploring across disciplines, from human and artificial systems to biology. The long-term objective is to develop a conceptual and algorithmic toolset for defining and evidencing functional roles and relationships in systems that are subjected to external selection, as a complementary approach to the better-understood optimization paradigm.
