Prein annual symposium gathered prein researchers from all research themes

The PREIN Annual Symposium was arranged on March 22- 24 on the Helsinki-Stockholm ferry. The event gathered more than one hundred researchers to present their latest research results and to increase the collaboration between the PREIN partners and the thematic works packages.

All the five work packages presented an overview of the current research themes, one to two research highlight based on a resent scientific breakthrough based on a high-level publication. The work packages had also invited top-notch international researchers as visiting speakers to present their research connected to the WP theme. The invited speakers included Michele Celebrano from Politecnico di Milano, Peter Kazansky form University of Southampton, Fen Gao form Linköping University and Leif Oxenlowe from DTU.

In addition, there was a short summary of the flagship activities by Goëry Genty, including the publication of the Annual Report 2022 and a presentation of PREIN impact activities by Juha Purmonen.
