About Welcome to my site. Here you will find summaries of my work, videos to watch, papers to download, images to study and links to pursue. I have three areas of interest - photography, multimedia and politics. I am particularly concerned with (1) how documentary photography, photojournalism and satellite imaging visually enact our world; (2) how multimedia technologies are transforming the capacity of photography to tell stories about our hybrid world; and (3) how issues of identity and representation help structure international politics. A full CV/resume is available here. As professor of cultural and political geography at Durham University in the UK, I am associated with the Durham Centre for Advanced Photography Studies. In 2009 I have a fellowship at Durham's Institute for Advanced Study to work on photographs from the Sudan archive for my 'Geopolitics and Visuality' project.

Geo-mapping how much we value photographs as tokens of "buzz" The proliferation of online photography and geo-tagging allows researchers to visualize and define a "geography of buzz". A new study of time-stamped, geo-tagged photos uploaded to the internet equates quantities and clusters of images as photographic tokens of cultural value. How will urban developers and event marketers tap into these power centers highlighted by stock photo agencies and citizen photographers uploading images to Flickr and Twitter? Very interesting reading in the New York Times, and the original research paper.

Globalization and the internet have created a space for news and political discourse that overrides geography and increases opportunities for non-mainstream, citizen-based news sources. Drawing a distinction between emerging citizen and professional media, this study examines one rapidly expanding and increasingly influential citizen news source - weblogs. We analyzed the linking patterns, the online network led to by six of the most popular news and political weblogs to study their relationship to other weblogs and the traditional professional news media in the USA and internationally. Findings suggest a more complementary relationship between weblogs and traditional journalism and less echo-chamber political insularity than typically assumed. The blogosphere relies heavily on professional news reports and half of its linked-to sites can be considered non-partisan.

"On the Internet, everybody is a millenarian. Internet journalism, according to those who produce manifestos on its behalf, represents a world-historical development-not so much because of the expressive power of the new medium as because of its accessibility to producers and consumers. That permits it to break the long-standing choke hold on public information and discussion that the traditional media-usually known, when this argument is made, as "gatekeepers" or "the priesthood"-have supposedly been able to maintain up to now. "Millions of Americans who were once in awe of the punditocracy now realize that anyone can do this stuff-and that many unknowns can do it better than the lords of the profession," Glenn Reynolds, a University of Tennessee law professor who operates one of the leading blogs, Instapundit, writes, typically, in his new book, "An Army of Davids: How Markets and Technology Empower Ordinary People to Beat Big Media, Big Government and Other Goliaths." The rhetoric about Internet journalism produced by Reynolds and many others is plausible only because it conflates several distinct categories of material that are widely available online and didn't use to be. One is pure opinion, especially political opinion, which the Internet has made infinitely easy to purvey. Another is information originally published in other media-everything from Chilean newspaper stories and entries in German encyclopedias to papers presented at Micronesian conferences on accounting methods-which one can find instantly on search and aggregation sites. Lately, grand journalistic claims have been made on behalf of material produced specifically for Web sites by people who don't have jobs with news organizations. According to a study published last month by the Pew Internet & American Life Project, there are twelve million bloggers in the United States, and thirty-four per cent of them consider blogging to be a form of journalism. That would add
