Thursday March 25, 2021 at 10:00-15:15 in Zoom
Organized by Tampere University

Please register by 24.3.2021  Registered participants will be sent a link to the on-line event.

All registered participants have been sent a calendar invite with the Zoom link. If you have not received the calendar invite/Zoom link, please contact Tea Vellamo (

Scope of the workshop:

  • Introduce project activities and technologies related to light sources at PREIN research sites
  • Present highlights of specific topics with high potential for collaboration
  • Introduce more researchers to the PREIN community – presentations by postdocs and PhD students forms the main part of the event
  • Discussion of common research topics and new project initiatives (in breakout rooms).
