This week's VisLunch session will be used to plan the semester or at least the first sessions of the semester. One practice that for these sessions is to use them as mean to let people know about the past or current work of the new people around: new PhD. students, new post. docs, new faculties. We should schedule these presentations during this session among the discussion of other topics. We are open to suggestion and to presentations of anyone who is willing to share their ideas.
