Personal profile

Research interests

Eric's expertise is on private law, law of civil procedure, and IT law. His current research focuses on

  • legal aspects of data and digital developments (smart contracts, property rights in data, liability for algorithms),
  • methodology of doctrinal research (from viewpoint philosophy of science/epistemology),
  • service contracts, professions and institutions,
  • multi-party contracts and networks.
In practice, multiparty agreements are a regular occurrence. Just think of consumers that sign a financing agreement with a bank through a dealership when they buy a car. Who is responsible if something goes wrong in such an agreement? In practice, judges will eventually find an answer, but they still seem to require a more solid legal footing. Another subject that I'm involved with is digitalization and private law. Suppose I pay to download an mp3. Who is the owner of that file? Intuitively, you would say that I am, but the legal answer is often a lot more complicated. It's interesting to examine to what extent the law is still suited to these kinds of current developments.
