Catherine Havasi co-created the Open Mind Common Sense project, as an undergraduate researcher working with Push Singh way back in 1999. For the last five years, she's been working on a doctorate in computational linguistics at Brandeis University. She's been doing a lot of cross-campus research with this group.
Last month, she finally earned her Ph.D (congratulations!). Now, she's returned to the Media Lab as a post-doc, where she'll once again be able to work on Open Mind and its applications full time. It's great to have her as an official part of the group again!
