Italian theoretical physicist, co-author with Andrea Sportiello 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 as co-author of the primary read directly to confirm
a figure repeated across a decade of secondary SOC literature — see
[[claim-caracciolo-sportiello-2012-confirms-17-8-average-height]], one of
the cleanest source-verification outcomes in the vault's
self-organized-criticality cluster.
