A random partition of the 3-sphere. In high dimensions many properties of the N-sphere are counterintuitive. These properties are important for the understanding of systems like e.g. the perceptron.

Scientific interests
I am using methods from the theory of disordered systems to understand emergent phenomena in complex systems like artificial neural networks or ecosystems.
