Registration is opening soon. Registration will close when the School is full (maximum of 100 participants), or on November 30th at 23:59, the latest. Please indicate in the registration form if you want to present a poster at the winter school, and/or if you wish to be considered for a contributed talk.

The School is free of charge for academic staff at any level: students, postdocs, as well professors are all welcome to attend the school.

The school is an in-person event, only. There will be no possibility for remote participation.

Please note that since the school is free of charge, we are unable to provide support for travel or accomodation costs. Please also note that we are unable to sponsor visas or provide invitation letters for the participants, since in the cases these are necessary, the visa process wouldn't even finish in time for the winter school.

REGISTER HERE

If you are able to submit the form, the registration form should tell you to go ahead with your travel bookings.

The School will commence on Monday, 15 December at 9:00 AM. Be on time!

We finish on Thursday, 18 December at noon, so please don't leave before this.

• List of Hotels in Helsinki

• Arriving at the airport, you can take the public bus 600 or the train connection between the airport and the central railway station with ringrail trains I and P. You need an ABC zone ticket, which you can buy from a vending machine, an R-kioski -shop or with the HSL mobile phone app. You might consider buying a four-day ticket (see tip below).
• Information about tickets for public transport (HSL): Link to HSL pages . To move around in the city center area, you will need to buy a AB ticket. However, for the airport you need a ticket for zones ABC. A four-day ticket for the ABC zone will cost 27,50 €. You can also buy tickets with the mobile phone app "HSL".
• The HSL app, The Journey Planner for public transport, and Google Maps might be helpful. Wikipedia knows about public transport in Helsinki as well.
• A taxi from the airport to the city centre should be around 40–50 €. Note: Taxi prices are unregulated, so a ride can in principle cost anything. Best to ask the driver beforehand. This applies to all taxi rides, not only from/to the airport. Note that Uber is legal in Finland, and we recommend using it to avoid any unpleasant surprises. Some Finnish taxi companies also have their own apps, but they are not as easy to use as Uber.
• Look at the latest weather reports before travelling as temperatures might drop below the freezing point for the Winter School week.

For the evenings, we have collected a list of places suitable for slightly larger groups. The ones in italics are also good for just a drink or three. There's also a more complete restaurant map. The organizers recommend

• Cella - a traditional restaurant in the Kallio district
• Elite - a traditional culture and artist restaurant
• CoolHead - a craft brewery on the Viikki campus that also serves pizza; especially famous for their sour beers
• Fat Lizard - a craft brewery restaurant in downtown Helsinki
• Manala - the place for late night eats
• St Urho's Pub - a pub close to the parliament building that also serves food from Manala's kitchen
• Juttutupa - one of the oldest restaurants in Helsinki
• Kaisla - a bar in downtown Helsinki with one of the best beer selections
• Konstan Möljä - traditional Finnish buffet
