All talks will be held in room KJL2 (map) in the Kjelhuset building on NTNUs Gløshaugen campus in Trondheim.

It takes about 20-30 minutes to walk between downtown and Gløshaugen campus. The most convenient bus routes are 3, 22 and 25 which stop at Høgskoleringen next to the campus (3 and 22 also continue on to the Gløshaugen stop, which is very slightly closer to the conference). A number of other buses stop at Samfundet, which is about a 10 minute walk from campus; see atb.no for details. The easiest way to purchase a ticket (and check the schedule) is to download the AtB app. Note that unfortunately the buses are running on a very reduced summer schedule from 26 June.

There are also city bikes with stations all over Trondheim; you can get a daily pass for these, but you need an app for unlocking them.


To get to Trondheim, the best option is to fly to Trondheim Værnes airport (TRD). There are direct international connections from Amsterdam and Copenhagen and a few other places, as well as many flights to Oslo. It is also possible to take the train from Oslo, but this is a long (albeit scenic) trip.

From the airport you can take the airport bus to the city (40 minutes) with Værnesekspressen; the bus stops near all major hotels in Trondheim. (There are also trains, which are significantly cheaper, but they only run once every 1-2 hours.)
