BUSM132 Complex Networks and Innovation

Dr Pietro Panzarasas


Module overview

This module focuses on the structure and dynamics of a variety of complex networks, including the Internet, the World Wide Web, online social networks, inter- and intra-organisational networks, and import-export trade networks among countries. The module aims to develop a unified theoretical framework for the analysis of sociologically relevant phenomena that exhibit complex network structures and dynamics, such as information diffusion, cultural fads, financial crises, and viral marketing. Special emphasis will be placed on innovation, with a view to uncovering the structural foundations of knowledge creation, transfer, sharing, and diffusion in various empirical domains. To this end, the module will develop an interdisciplinary perspective by combining current research on complex networks with contributions from relevant organisational and sociological research.
