This will be a packed event that we are sure will make it worth your while to participate in. Below is an overview of the programme (with an interactive version coming as soon as participants and respective session programmes are finalised). There will also be “unconference sessions” on the side which will allow for talks to be proposed and voted upon by participants during the event, ensuring a dynamic component that caters for current trends/interests and the very latest scientific developments.
