Lois Beckett has been a reporter for ProPublica since 2011. She covers the intersection of big data, technology and politics. Her recent work focused on the role of data analysis and targeted advertising in the 2012 campaign. Her story on Minnesota’s data-collecting “Grandma Brigade” looked at how sophisticated modeling techniques still depend on old-school local organizing. Before joining ProPublica, she wrote for the SF Weekly and the Nieman Journalism Lab.
