- Started a mailing list for machine learning in the Netherlands
- Adaptive methods in online convex optimization and prediction with expert advice
- Faster-than-minimax rates for ‘easy data’ in statistical and online learning
- Statistical learning theory, frequentist analysis of Bayesian methods
- PAC-Bayesian concentration inequalities
- Information theory in statistics, minimum description length
- Model selection
