Italian theoretical physicist, co-author with Sergio Caracciolo of "Exact
integration of height probabilities in the Abelian Sandpile Model" (2012,
arXiv:1207.6074), which provided the first analytic proof of Grassberger's
conjecture that the two-dimensional model's average site height is 17/8.

Matters to this vault for the same reason as his co-author: the paper the
two of them wrote together is the direct primary behind
[[claim-caracciolo-sportiello-2012-confirms-17-8-average-height]].
