In Trieste

I am at the Abdus Salam International Center for Theoretical Physics (ICTP) in Trieste, Italy. I am teaching about 60 students from all over the world (really from all over, not only from Europe and North America) my class on scientific computing. It is really great to interact with these students, plus, this is the view from my room! (not to mention the excellent coffee) ICTP view

Reactivity & Stability

After studying the stability of large ecological networks, we wanted to try to describe the transient dynamics following a small perturbation of the equilibrium. We thus studied “reactivity”, which tells us whether perturbations of a stable equilibrium are going to be amplified before decaying.

The paper is now out:

Si Tang & Stefano Allesina
Reactivity and stability of large ecosystems

which we published in frontiers in Ecology and Evolution, a new journal with an interesting peer-review scheme (a topic dear to my heart!). In fact, I am so happy journals are trying new ways of doing peer review I decided to join the editorial board.
