About
Professor at NTNU/IDI since aug 2001 in distributed systems with focus on databases and search engines. Previously employed in Clustra which developed highly available, scalable real-time databases. In the years 2007-14 I worked on the SFI iAD - information access disruptions, where Microsoft was the centre leader. This was work on next generation search engines, where the focus at NTNU was on scalabale indexes and structured queries. The research focus now is on velocity in Big data.
I am currently involved with the SFU Excited
My courses are the following:
TDT4145 Data modeling and database management systems (500 students)
TDT4225 Very large, distributed data volumes (200 students)
TDT02 Advanced, distributed systems (15 students)
