We have a few extra photos lying around from Saturday’s commencement ceremonies at Notre Dame de Namur University in Belmont. In the photo above, Yang Zhou holds her 1-year-old son Raymond.

Former teacher-astronaut Barbara Morgan, above, was the keynote speaker. Morgan, who got her teaching credential at Notre Dame de Namur in 1974, was a member of the space shuttle Endeavour crew that performed a two-week mission in 2007, making improvements to the International Space Station.

Derek Joseph DeGrenier, above, waved to friends during the commencement ceremonies.
