Third Year Academic Advisor
Pietro Panzarasa’s research is concerned with the field of complex networks, and focuses primarily on the structure and dynamics of social interaction. The general goal of his work is to better understand the antecedents, structure, functioning, and implications of complex large-scale networks. Recent work has examined the topological properties and growth mechanisms of weighted and dynamic networks in a variety of empirical domains, including scientific collaboration, online communication, technological and transportation systems. Ongoing projects investigate communities and patterns of scientific collaboration in large-scale co-authorship networks, interdisciplinarity and specialization in scientific production, social capital and the effects of social cohesion and structural holes on innovation and knowledge creation, the effects of homophily and social dependence on social interaction, and patterns and dynamics of e-learning usage in medical education. His work is also concerned with fundamental network properties such as assortative mixing in signed networks, centrality measures in multiplex networks, brokerage, and rich-club orderings in weighted networks.
