On behalf of Ji Li (Macquarie University): Dear All, On Friday afternoon (27 Oct 2017), we will have the tenth Department Colloquium Series talk for this semester: 3-4pm, ACE room: E7B 146, Speaker: Dr. Daniel Hauer from The University of Sydney. We will take the speaker to lunch at the Staff Cafe, and will depart from our department (from outside of the kitchen in E7A level 7) at about 12:30pm. After the talk, our department provides some light refreshments in the kitchen in E7A level 7, organised by Christine. You are all welcome to join us. I have attached the title and abstract for your convenience (see the pdf file in the attachment).
