Research

Professor Haentjens is primarily interested in property law, tort law, private international law and Supreme Court litigation. His research focuses on how traditional systems of law cope with modern developments such as digital assets and emission rights. The interaction between EU law and national private law, and between private law and public law, is another key area of interest. Is our private legal system prepared for the next few decades, and when we will have to address climate change and digitalisation?

Professor Haentjens’ key publications include his legislative advice for the Assocation of International Insolvency Law ‘COVID-19 as a stress-test for insolvency law’ (2021, in Dutch), his book ‘Financial Collateral: Law and Practice’ (Oxford University Press, 2020) and his inaugural address at Ghent University entitled ‘Incoherence United, Private Law Concepts under Pressure of EU Financial Law’ (Tijdschrift voor Privaatrecht 2017/III, in Dutch).

His research is part of the Coherent Private Law research programme.
