While at MIT, Castells’ research focused on the role of communication technologies in shaping society. He developed the concept of “network society,” which describes the interconnectedness of individuals and communities facilitated by the Internet and other digital technologies. This concept has been widely influential in the field of sociology and has helped us better understand the ways in which technology is changing our world.

In the 1990s, Castells returned to his hometown of Barcelona, where he became a professor of sociology at the University of Catalonia.

His theory of the network society has been particularly influential, providing a framework for understanding the new ways in which people are connected and organized in our digital age.

Another major contribution of Castells’ work has been his analysis of the power structures that underlie modern society. He has argued that power is not just held by governments and corporations but is also distributed among social networks and communities. This perspective has helped to foreground the ways in which individuals and groups can resist and challenge dominant power structures, leading to more democratic and equitable societies.

Castells’ research on urban sociology has also been groundbreaking, providing insights into the social dynamics of cities and the challenges faced by urban communities. His work has explored issues such as gentrification, urban regeneration, and the role of social movements in shaping urban development. This research has been critical in informing policy and practice in the fields of urban planning and community development.

More broadly, Castells’ work has contributed to a deeper understanding of the social and political challenges facing our world today.
