And to compound the honor of our social mobilization work being published in PNAS, we also had work on a related topic published in IEEE Computer magazine this month. It was complemented in the same issue by an editorial piece "Equal Before the Bar", written by David Alan Grier himself, in which he describes his role in our victory, and why it is significant to the field of study. This one was about the US State Department Tag Challenge, a social mobilization challenge that our lab played a leading role in winning as Team CrowdScanner (web application developed by me for the challenge).

From the article:

Using social media and only the targets’ mug shots, a team competing in the
US State Department-sponsored Tag Challenge located three of five targeted
people in five cities in the US and Europe in less than 12 hours.
...
The Tag Challenge was significantly harder than the
Red Balloon Challenge because it required locating people
in highly populated cities, where the pace of life can help
people “hide in plain sight,”
 and making it much more difficult to spot the suspects than to find large red balloons.
Furthermore, people are mobile, making it difficult to rule
out locations that have already been visited.
