Dr. Lee Gray, Senior Associate Dean for Academic Affairs and Professor of Architecture, was featured in a segment on National Public Radio’s Here & Now, which aired April 18. The segment, “What’s the most efficient way to ride an escalator?” began with a discussion of a study done by the London Underground on the most efficient way to move large numbers of people on escalators as they exit the subway station. Hobson’s nine-minute interview with Gray then explored the history of escalators and interesting facts about their operation. Listen to the full interview here.
