In honor of fallen MIT police officer Sean Collier who died in the line of duty in 2013, a permanent campus memorial in his name now stands at the intersection of Vassar and Main Streets. On Monday, April 27 at 6pm in room 10-250, CEE Professor John Ochsendorf will present a lecture about the collaborative efforts to design, engineer and construct the memorial as well as explore the way the team merged stone-setting techniques with robotic fabrication technologies in the construction. The public dedication of the Collier Memorial will take place Wednesday, April 29, beginning at noon on the North Court near the site of the memorial. For the full story, please see here.
