Plannerry. I think when we were planning the conference, we always like to bring our heavy hitters out. And i think today is one of those occasions in which we have a collection of fine scholars and activists here to address our theme. So what we decided to do is run the plannerry more as a roundtable, as a moderated conversation about issue with the great migration. And i wanted to introduce our panelists and give them an opportunity to speak for a few minutes as far as their own work and their perceptions and ideas about the great migration and then move on into a question and answer followed by a discussion with us and followed by a question answer session with the audience. So i want to introduce our panelists. Our first pannestist is joe trotter who is a giant eagle professor of history in social justice and past History Department chair at cornegy university in pittsburgh. He is also the director and founder of the cornegy center for africanamerican urban studies in economy. Hes
