Biography

Birke Häcker holds the statutory Chair in Comparative Law. She is the Director of the Institute of European and Comparative Law and a Professorial Fellow of Brasenose College.

Prior to taking up her position, she was a Fellow of All Souls College, a Senior Research Fellow at the Max Planck Institute for Tax Law and Public Finance in Munich, and a Lecturer in Law at Ludwig-Maximilian-University Munich (awarded the Therese von Bayern Prize 2015). As an undergraduate, she obtained a dual legal education, reading Jurisprudence at Oxford as well as German law at the Universities of Tübingen and Bonn. Her Oxford DPhil is on comparative private law (Consequences of Impaired Consent Transfers: A Structural Comparison of English and German Law, published 2009, republished 2013). She is qualified to practise in Germany. 

Professor Häcker's main research interests lie in the field of private law, with a strong comparative and historical focus. This includes especially contract, tort/delict, restitution for unjust(ified) enrichment, property, trusts, and succession, but also extends to adjoining areas of commercial and company law, aspects of tax law, as well as the principles governing the conflict of laws. Besides analysing the traditional 'common law / civil law divide' and comparing different civilian systems with one another, a specific research focus lies on examining the relationship and increasing divergence of common law systems around the world and thinking systematically about the 'comparative common law' phenomenon (both in terms of black letter law and methodology).

At Oxford, Professor Häcker teaches the course options Comparative Private Law as well as Comparative Contract Law in Europe. She also lectures on European Private Law, comparative law theory and methodology and offers various classes introducing Civil Lawyers to the Common Law tradition.  

She is a Council Member of the British Association of Comparative Law (BACL), a Fellow of the European Law Institute (ELI), a Research Affiliate at the Max Planck Institute for Tax Law and Public Finance, and an Academic Member of the Chancery Bar Association. In the past, she has held visiting positions at the Australian National University in Canberra (February-March 2009), at Singapore Management University (August 2019), and at the University of Paris 1 Panthéon-Sorbonne (Visiting Professor 2017-2019).
