The conference will take place in lecture hall H51 in the south of the campus. You find it on the University Map between the labels "Pre-clinical Medicine" and "Sports Center"
There are many useful buses typically, but the 6 will suffice for getting to and from the city center and the conference hall (nearest stops are either 'An der Kreuzbreite' or 'Neuprüll'). There should be signs pointing to the lecture hall. One can also walk from the 'Universitat' bus stop, which is better served by the bus system. Check the bus schedules at the public transport organisation's website.
You can pay for a bus ride on entering the bus or purchase a strip of tickets from one of the ticket machines. A strip of tickets costs 9.00 euros and it allows five bus rides.
