SCA & ARCA Global Conference 2020 – Abstracts


We selected 24 abstracts to be presented as Flash Talks (5 minutes pre-recorded presentations) during the conference. All abstracts are published in the conference brochure. The best presentation from each Flash Talk session was awarded. The winners were: Andreas Traschütz, Celeste Stuart, Jeannette Hübener-Schmid, and Jennifer Faber.

All pre-recorded flash talks (in some cases only the abstracts) can be found on the programme & recorded sessions section here.
