Duncan J. Watts studies graphs and collective behavior using mathematical models, experiments, and large-scale data. His 1998 work with Steven H. Strogatz introduced the Watts-Strogatz model, showing how a few rewired connections can greatly shorten paths in an otherwise locally clustered graph.[ref]

This gave a concrete explanation for how high clustering and short path lengths can coexist. His institutional biography describes research on social and organizational graphs, collective dynamics, and web-based experiments, alongside training in physics and theoretical and applied mechanics.[ref]

Duncan J. Watts is a notable American sociologist, best known for his work in the fields of social networks, complex systems, and the dynamics of social behavior. He gained significant recognition for his research on the structure and dynamics of networks, particularly the "small-world" phenomenon, which he explored in his influential paper co-authored with Steven Strogatz in 1998.
