Hello World!

I’m Lorenzo, Post Doctoral researcher at Free University of Berlin, in Prof. Cecilia Clementi’s group. I am particularly fascinated by how many interacting objects can lead to some unexpected and complex behaviors.

I’ve been particularly focusing on Simplicial Complexes and Deep Learning, exploring the diverse facets of both fields. In the realm of Simplicial Complexes, my interest lies in the intricate relationship between topology and dynamics. As for Deep Learning, my focus is on pinpointing the exact location of information within a Neural Network (NN) and figuring out how to make these networks as compact and efficient as possible.

The way I try to make sense of all this is through spectral properties of the operators involved and, more recently, with statistical mechanics.

In my free time, I love to roam around on my mountain bike, nurture my plants, play the guitar, and practice Kung Fu.
