Cozzarelli Prize awarded for groundbreaking research

Alongside Dr Francesco Caravelli (Los Alamos National Laboratory) and Dr Pierpaolo Vivo (King's College London), Dr Bartolucci and Prof Caccioli have been recognised for their groundbreaking work in understanding the structure and functionality of complex networks. 

What makes a node in a network truly important? This Cozzarelli Prize-winning research introduces a new method to estimate centrality in large-scale networks. Using the cavity method, researchers show that a node’s importance closely correlates with its number of connections, offering a powerful tool for analysing everything from transportation and power grids to financial and biological systems.

The Cozzarelli Prize is awarded annually to six PNAS articles that represent outstanding scientific excellence and originality. This study received the Cozzarelli Prize for Class III: Engineering and Applied Sciences, one of six disciplinary categories of the National Academy of Sciences.

Dr Bartolucci said, "It is a great honour to receive the Cozzarelli Prize and see our theoretical contributions to complex systems research recognised for their potential to deepen our understanding of complex real-world network organisation. Identifying structurally and functionally critical nodes is essential for designing targeted interventions and maintenance strategies that sustain network functionality. I am truly grateful to my collaborators for their insight and the enriching journey we have shared on this project."
