It is part of our contribution to the university/faculty’s outreach efforts and as such we all stand to benefit from the success of this event. It will take place on Monday, 26 March from 6-7:30pm in the General Lecture Theatre of the Quadrangle. You and your friends/family are all warmly invited to join us that evening.
