Alice Niemeyer is back from an extended visit to the RWTH Aachen, Germany.
The Centre had its first ever research retreat, in Yanchep on 11 - 14 April 2012. Staff and students worked together on problems, forming new collaborations. We are now working on several of the problems discussed and hope to get a few publications as a result of this trip. This was a very successful venture and we hope to make it an annual event. The event was attended by John Bamberg, Brian Corr, Alice Devillers, Michael Giudici, Wei Jin, Cai-Heng Li, Sylvia Morris, Guang Rao, Gordon Royle, Akos Seress and Anne Thomas (University of Sydney).
Alice Devillers visited James Parkinson at the University of Sydney in December 2011, and worked with James and Hendrik Van Maldeghem.
