Midsummer greetings from the HEPP4 organising committee and registration update

It is now a warm Midsummer in Finland ("Juhannus" in Finnish) in contrast to the much different weather we're expecting for the HEPP4 Conference in December, to which we recently sent out our invitations. We are glad to share with you that we received an unexpectedly large number of high-quality submissions from researchers and experts in various fields. Thanks to everyone for their valuable contributions.

We are happy to announce that registration for the upcoming HEPP4 conference is now open.

We would like to remind you that early bird registration is open until 6 July 2023. After that, standard registration fees apply. Regular registration is open until 15 September 2023.

Reduced fees apply to doctoral researchers, non-employed researchers, and colleagues from the Global South and Central and Eastern Europe:

  • HEPP4 ONSITE: Normal fee – 250€ (early bird 200) 
  • HEPP4 ONSITE: Reduced fee – 150€ (early bird 120)

Once again, do not forget to check out our latest updates about the post-conference symposium day on 14 December 2023 at the University of Lapland in Rovaniemi and its preliminary programme to make up your mind and decide if you join us up north. Though we would remind that the symposium day takes place during high demand Christmas season in Lapland meaning you should try to book your travel plans early.
