Annual Research Retreat
The annual CMSC research retreat took place in June (winter!) this year. Once again, we stayed in the Moondyne Country Convention Centre in the marvellous Avon Valley and enjoyed the exceptional hospitality of our hosts Christine and Peter. For the first time, we saw the Avon Valley green and the river gushing. We had two external visitors this year: Alice Niemeyer (RWTH Aachen, Gemany) and Stephen Tornier (University of Newcastle, NSW). Altogether, this year's retreat had 10 participants, who worked on 7 problems, We look forward to sharing our insights in the form of publications, and to returning to this very productive research event next year as well.
For an up to date list of visitors, see here.
