The IDDRG is strongly committed to support and save all the members of the IDDRG community, therefore the IDDRG Executive Committee in accordance with the local Organising Committee decided to have a Virtual Conference in 2020 between 26-30. October. The IDDRG is committed to preserving the long history and high standards of the IDDRG Conferences. Although, the 39th IDDRG Conference will look and feel a little different, the tradition of connecting our community through a virtual platform promises to be an exciting experience. We welcome you to join us in this new endeavour, a Virtual 2020 IDDRG Conference. Two special tutorial sessions will also be organised with outstanding scientists.
