Professor Bernhard Pfahringer

Dipl.-Ing. TU Wien, Dr.techn. TU Wien


Bernhard received his Dr. techn. (~ PhD) degree from the University of Technology in Vienna, Austria, in 1995. In Vienna he was a research fellow with the Austrian Research Institute for Artificial Intelligence from 1985 to 1999. From 2000 until May 2017 he was affiliated with the Department of Computer Science at the University of Waikato, going from Senior Lecturer to Professor, and also serving as the Head of Department for about 4.5 years. He joined the University of Auckland in June 2017.

Research | Current

I am fascinated by analysing data, uncovering useful information and knowledge. I love developing and improving algorithms for this purpose. My research interests span a range of data mining and machine learning sub-fields, with a current focus on streaming, randomization, and complex data.
