and its effects on
dynamical processes
on networks
We study complex networks from different domains: social networks, the
human brain, transport networks, genetic systems…
1. Data on a network is collected
3. Simulations are conducted to understand how network
structure affects processes (e.g. information flow)
2. The structure and time
evolution of the network
are examined; these reveal
a lot about the function of
the network
Examples of research
questions:
• How do our social
networks change in
time? Are there
features that do not
change? Why?
• How to design a
network (e.g. of
public transport)
that is very error-
tolerant and resilient
to problems?
