What matters about Preston Scott Cohen, a Harvard professor of architecture and digital wunderkind, is not that he is a consummate academic with piles of paper shoved into his pocket or that he turned up late to deliver a lecture at Toronto's Bader Theatre because of a corrupted CD. What matters is that he is an architect in love with geometry. Cohen, 42, is the new holder of the Frank Gehry international visiting chair in architectural design at the University of Toronto's faculty of architecture, landscape and design. He'll teach graduate students over the next four months. "I want to bring them to the thought that the problem of the actual shape of buildings is not one that we can determine -- that we need to invent our own problem."
