With heavy heart, the international steering committee has decided that PRAHA2020 is postponed, to become PRAHA2022. We are grateful to the local organizers for accepting to host the postponed conference from 29.08.2022 to 02.09.2022 in Prague.


Sadly - because of the on-going SARS CoV-2 pandemic - we have to miss the 50-year Golden Jubilee of the series (the first was held at the Czech Technical University Prague in September 1970) and the 50th anniversary of the pioneering, influential publication by J. T. Hougen, P. R. Bunker, and J. W. C. Johns also known as the HBJ-paper. On the positive side, the spirit of these authors will live on in the spirit of the future edition of this conference.


We wish all of you the success and luck that is needed to make it through these difficult times and we are looking forward to welcoming you at PRAHA2022! Same venue, with new dates : 29.08.2022 to 02.09.2022.


More information on the conference will be available at our PRAHA2022 website in Fall 2021.
