Robert Ackland is a Fellow at the Australian National University. He works
on the development of new approaches (and associated software) for
empirical social science research into online social and organizational
networks, and has recently studied the networking behavior of political
bloggers and environmental activists. Robert has degrees in economics
from the University of Melbourne, Yale University (where he was a
Fulbright Scholar) and the ANU, where he completed his PhD in
economics in 2001.
In 2005 he established the Virtual Observatory for the Study of Online
Networks (http://voson.anu.edu.au) project and in 2007, he was awarded
a UK National Centre for e-Social Science Visiting Fellowship and an
Oxford University James Martin Visiting Fellowship (at the Oxford Internet
Institute). Robert coordinates the ANU's Master of Social Research
programme and teaches courses on the social science of the Internet and
online research methods. He is currently writing a related book (to be
published by SAGE).

NodeXL visualization of the local hyperlink network for the VOSON Project
(filtered). Seed sites are solid squares (except for the VOSON Project web site,
which is a solid triangle), whereas other sites are discs. Vertex size is proportional
to in-degree and vertex color corresponds to generic TLD (.edu, turquoise; .org,
blue; .com, red; and .net, brown).
