Mark Henry Hansen (born 1964) is an American statistician, professor at the Columbia University Graduate School of Journalism and Director of the David and Helen Gurley Brown Institute for Media Innovation.

[9] In 2012, he joined Columbia's Graduate School of Journalism as a professor, and as Director of the David and Helen Gurley Brown Institute for Media Innovation.

Mark Hansen and Ben Rubin were partners in the creation of Moveable Type, on display in the lobby of the New York Times building in midtown Manhattan from November of 2007.

Over the bar in the center of the lobby of the Public Theater in New York City, the team constructed a chandelier, a digital display consisting of 37 LED panels, one for each of Shakespeare's plays.

[32][33] Hansen and Rubin collaborated with the Elevator Repair Service and Rebecca Mead to create the theatrical performance Shuffle drawing from the texts of The Great Gatsby, The Sun Also Rises, and The Sound and the Fury, each used previously as a script for an ERS production.

[34] As the Office for Creative Research, Thorp, Hansen and Rubin produced a second piece with the Elevator Repair Service through the Museum of Modern Art's Artist's Experiments Program.

ERS actors received randomized scripts drawn from the titles, artist names, materials and dimensions of the artworks in MoMA's collection.

[36] The installation pulls articles from over 100 news sources to create an ever-evolving timeline of the social, cultural, political and economic impacts of the 9/11 attacks that are still felt today.

In 2010, Hansen collaborated with Jer Thorp and Jake Porway to create Project Cascade, a tool to visualize connections between articles shared on Twitter.
