Derek Rogers is a computer science student at Dalhousie University in Halifax, Nova Scotia (Canada). I met him in Washington last April. He has been active in the atheist bus campaign and other events promoting a nonreligious point of view.
Derek was at the Secular Student Alliance meeting in Ohio and went along with the group that visited the creation museum. He was asked to leave. Here's the video of him explaining what happened to PZ Myers, Seanna and Steve Watson, and others who had just toured the museum.
