    Administration, outreach and other activities

    Current commissions of trust. Increasingly, I am involved in the development of national as well as European marine research networks, which also includes infrastructure networks.

  • FINMARI (Finnish marine infrastructure network) management group

  • Coordinator of the Finnish efforts (on behalf of University of Helsinki, University of Turku, Åbo Akademi University) towards membership in EMBRC, European Marine Biology Research Centre (a distributed research infrastructure on the ESFRI roadmap)

  • Member of the core team in the strategic collaboration between the University of Helsinki (TZS) and Stockholm University (Baltic Sea Centre)

  • EuroMarine General Assembly (substitute)


    Outreach. At TZS, I have an important role in outreach, information and media contacts. I am responsible for the station’s webpage (launched in December 2016), providing information for researchers and students coming to do science at the station, students attending courses, information for potential collaborators and sponsors, and outreach to the general public. I am also responsible for the TZS Facebook page and the development of an online data portal for a project called MONICOAST (launched in spring 2017).



Editorial and reviewer assignments for international journals and funding agencies

Editor: Member of editorial board of ICES Journal of Marine Science (2015 - )
