[4eyes] [grads] PhD Defense - Steffen Gauglitz - 7/14/14

[Chris Sweeney]

Steffen -- would it be possible to send out a video conference/go to
meeting link for your defense so that people in the lab that are at
internships can watch? I imagine Gerhard will already be using something
like this anyways...
