Symposium on the occasion of Odd O. Aalen's 70th birthday

Odd O. Aalen's contributions in fundamental concepts, methods, theories and instruments to modern statistical science during his long career are highly valued. He has been a key person in establishing biostatistics as a strong research field in Norway. On the occasion of his 70th birthday, colleagues, friends, collaborators, supporters and admirers wish to celebrate Odd with a symposium in his honour. The symposium will take place on the 11th and 12th of October, 2017, at the University of Oslo.

The talks will cover current topics in survival analysis, causal inference and infectious disease modelling.

From Oslo central station

Tram (Currently bus+tram)

Exit through the main entrance, cross the road in front of the station, and turn right to arrive at the tram stop. Take tram no. 17 (direction "Rikshospitalet") to the last stop, which is "Rikshospitalet." There are ongoing roadworks, so there is currently a "bus-for-tram" service between this stop and "Holbergs plass". Change from bus to tram 17 (direction "Rikshospitalet") on "Holbergs plass."

As the tram is approaching the last stop, Domus Medica is located to the left.


Inside the departure hall, follow the signs with a "T." Head to the platform for trains going west. Take line 5 "Sognsvann" or "Ringen" to the stop "Forskningsparken." Take tram 17 (direction "Rikshospitalet")  to the last stop.

Inside Domus Medica

As you enter the main entrance, take a left, and walk straight ahead untill you reach café "Eric" and the auditorium on your right hand side.


The symposium is hosted by the Oslo Centre for Biostatistics and Epidemiology (OCBE), Department of Biostatistics, University of Oslo, with support from the Norwegian Statistical Association (NSF).

Organizing committee

Ørnulf Borgan, Department of Mathmatics, University of Oslo, and Jon Michael Gran, Arnoldo Frigessi, Marit B. Veierød, Morten Valberg and Hilde B. Liudalen Oslo Center for Biostatistics and Epidemiology, University of Oslo and Oslo University Hospital.
