Field of researchEdit
Andenas is involved in research projects concerning European private law, including company law, the relationship between national law and European and international law, comparative constitutional and human rights law and constitutional aspects of the EU and the WTO. One main current research interest is the role of rule of law and rights concepts in the implementation of international human rights standards and the development of court remedies.
- Having a doctorate from both Oxford and Cambridge makes Andenas what Ghil'ad Zuckermann calls an "Oxbridge Paradox". Andenas belongs to the rare group of people who hold a "pair o' docs" (sounding like "paradox" but meaning "two doctorates"), a D.Phil. (Oxon.) and a Ph.D. (Cantab.), from both Oxford and Cambridge universities (commonly abbreviated as Oxbridge) - see -->Biography.
