I’m a Ph.D student at Technische Universität Berlin, at the DAI lab. Previous to this I was a student at Chalmers University of Technology.
From October 2010 to December 2010 I was a research intern at Talis in Birmingham, England, where I worked on distributed algorithms for recommendation in large datasets. The main part of my work consisted of implementing a MapReduced version of PLSA.
I am or have been involved in the following projects:
- KMuLE: Context-based Movie Recommendation – with Moviepilot.
- Decision Cockpit: Quantitative Real-Time Organizational IT Risk Management – with T-Labs and Stanford University.
- SPREE: Community-Based Information Exchange Network – with T-Labs.
