Twice a year, Olin College of Engineering in Needham hosts a free, end-of-semester exposition of student work.  The public is very much encouraged to attend.  The Fall 2015 Exposition on December 21 runs 10AM-3:30PM with poster sessions, presentations, performances, and lunch.  The list of presentations and performances will be available on the expo site the week before the event, but you can see last spring’s list here.  Register by December 18.  For information, email expo@olin.edu.
