Glen Whitney is passionate about every part of public mathematics — engagement, appreciation, and informal learning. After graduating from Harvard in 1989, Whitney did his graduate work in mathematical logic at UCLA and received a Ph.D. in 1994. He was on the faculty of the University of Michigan and subsequently became an applied mathematician at the quantitative hedge fund, Renaissance Technologies. In 2008, he left Renaissance and founded the National Museum of Mathematics in New York City. The museum opened its doors to the public in December 2012 and has sparked the interest of over a million visitors. Whitney continues to work on a variety of projects, promoting public mathematics in fresh and innovative ways.
