Life and work
Duncan Watts was born in 1971. He received a B.Sc. in physics from the University of New South Wales
and a Ph.D. in theoretical and applied mechanics from Cornell University
. He describes his research as exploring the "role that network structure plays in determining or constraining system behavior, focusing on a few broad problem areas in social science such as information contagion, financial risk management, and organizational design. Among his many published works he is particularly known for his 1998 paper with Steven Strogatz
in which the two presented a mathematical theory of the small world phenomenon
. More recently he has attracted attention for his modern-day replication of Stanley Milgram
's small world experiment
using email messages and for his studies of popularity and fads in on-line and other communities.
