Research Interest

In a society in which we are almost always “connected”, the capability of acquiring different information has become a source of huge amounts of data to be elaborated and analysed. Graphs are data structures that allow to model the relationships in these data, abstracting from specific and particular aspects and representing effectively millions or billions of connections: the complexity of the involved entities is enclosed in the vertices of the graphs and the complex mechanisms of interaction among them are described by an arc. For example, a social network can be seen as a graph whose nodes are the users and whose edges correspond to the friendships among them. Analogously, the economy of Bitcoin (or of any other economic system) corresponds to a graph whose nodes are the users and whose arcs correspond to payments among them. In such a context, discovering the most important or influent users, which ones will be their future friendships, which communities they belong to, and which is the structure of their society can be translated into problems on graphs. The research in this field focuses on developing models and algorithms to solve this kind of problems in efficient way on real-world graphs of large size. In particular, the research moves along two orthogonal axes: the former is devoted to the translation of a real-world problem in terms of a problem on graphs; the latter is aimed to develop efficient algorithms to solve the graph problem, possibly with (quasi-)linear time complexity. In this sense, theory and practice proceed together, as practical problems motivate contributions to theoretical computer science, which in turn allow efficient, useful, and practical solutions to the original problems.

Activities and Highlights

Author of a book, conference papers, and journal papers on graph algorithms with applications to enumeration, web crawling, bioinformatics, real-world graph analysis, information retrieval, mobile ad hoc networks, and computational linguistic.

  • Enumeration Algorithms: Author of a book (published by Atlantis Press, 2015) and other publications in this field. Co-author of the current best algorithm to list all the paths and cycles in a graph (SODA 2013), improving Johnson Algorithm (1975). Co-author of the current best output-sensitive algorithm to list all the maximal cliques in a graph (ICALP 2016). Coauthor of other several state of the art algorithms for listing basic structures of graphs and coauthor of general frameworks (MFCS 2018 and SIDMA 2019).
  • Algorithms for Real-World Graph Analysis: Co-author of state of the art algorithms to compute: diameter, hyperbolicity, and top-central nodes (closeness centrality) in huge graphs. The diameter algorithm (TCS 2013) has been used to compute the diameter of Facebook networks (1.2 billions of nodes) by Backstrom, Boldi, Rosa, Ugander, and Vigna in “Four degrees of separation” (WebSci 2012) (reported by The New York Times, (325):B1, 21 November 2011). More recently, interested in algorithms for temporal graph analysis extending notions and algorithms of classical graph theory to temporal graphs.
  • Bitcoin Graph Analysis. In a Bitcoin network, the nodes are user addresses and each edge represents a transaction from a payer address to a recipient one. Understanding Bitcoin economy and dynamics often translate in measuring properties of these networks. In this context, we have measured how the concentration of richness change over time, showing that “Rich get richer and poor get poorer” and the presence of artificial patterns.
  • Web Crawling: One of the BUbiNG developers; BUbiNG is the publicly available web crawler currently with the highest performances (downloading, storing, and managing billions of web pages), developed at LAW (Laboratory of Web Algorithmic), University of Milan.
  • Bioinformatic: Collaborator of INRIA (Institut National de Recherche en Informatique et en Automatique) BAMBOO & BAOBAB Team,Université Claude Bernard (Lyon 1), headed by Marie-France Sagot, working on metabolic networks and NGS (New Generation Sequence), designing ad hoc enumeration algorithms.
