Back in Berlin since summer 2009 I am teaching the general course on European law as well two specialized courses for advanced students the Specialized Program on The Law of the European and the International Community at the Law Faculty of the Humboldt Universitat zu Berlin. I am also teaching an on-line course in the EOA-Masters Program on European Law and guide the law-program of the French-German Master of European Goverance and Administration (MEGA). As the Speaker of the interdisciplinary DFG doctoral research group "Multilevel Constitutionalism. European Experiences and Global Perspectives" of Humboldt-University, sponsored by the German Research Fund, I have sucessfully applied for the second phase-of this program (2010-2015). My research on Europeanl constitutional law focusses on a textbook on European Law. I am advising the European Central Bank on the cases regarding the Financial Market Stability Measures, pending before the German Federal Constitutional Court. I was advising the German Government on the new EU law regarding Bilateral Investment Trieaties, and participated to the Fourth Luxembourg Expert Forum on the Development of European law with a contribution on the future of the European Court of Justice. Together with Jose Marfa Beneyto I am organzing the nineth international ECLN-Symposion on European Constitutional Law in Madrid (2010), with my own contribution on "MOTOR OR BRAKE FOR EUROPEAN POLICIES? Germany’s new role in the EU after the Lisbon-Judgment of its Federal Constitutional Court".
LAPA gave me an incredible insight in American Academic and political life. And the personal environment including not only a wonderful team but also most stimulating other LAPA fellows and colleagues at the fourth floor of Robertson Hall allowed me to taking a deep breath of academic air and broadening my horizon as from Biotechnology over American constitutionalism up to the most fascinating electoral campaign with the reaction of Princeton to the victory of Barack Obama. During my LAPA Fellowship, I was primarily working on questions of European Constitutionalism, in particular regarding the ratification problems of the Treaty of Lisbon, and on my specific project exploring the emergence of what may be called "global constitutionalism" in terms of constitutional theory. This led to an article published in the Columbia Journal of European Law (2009), and to a number of projects regarding constitutional matters of European Integration preparing a book on European Constitutional Law, on the one hand, and to further collection of materials and some drafting for a book on Global Constitutionalism, on the other.
