The Chair's scholarship aims at enhancing the understanding of existing law and its institutions as well as at evaluating ongoing projects of law-reform from a consequentialist perspective.The evaluation of both interpretatory and legislatory alternatives applies a methodology that is hospitable for the models and insights of social and cognitive sciences. On these grounds, increasing attention is devoted to empirical studies that go beyond the collection of descriptive data and employ methods of statistics and econometrics that allow to determine causal relations and interdependencies within institutional settings. Normative considerations are mainly targeted on the guiding idea of increasing overall social welfare. The outlined research activities are reflected in interdisciplinary and cross-jurisdictional collaborations and alliances. Regular participation in pertinent discussion groups and seminars ensures that research results and topics also reflect the views and needs of legal practitioners.
Research topics focus on various aspects of corporate, banking and contract law. In these areas not only traditional questions are analyzed  from the delineated perspectives, but also new developments are critically accompanied from the respective angle. In corporate law the possibilities and limits of supranational harmonization will be explored. The alternative of regulatory competition among national regulators and/or public regulators and private standard setters respectively will be considered as well. In addition, various legal institutions of organizational and securities law will be (re-)examined using current economic theories of the firm and capital markets. In banking law, substantive regulation and its enforcement will be analyzed with a particular view to the sustainability of the financial architecture. Research will focus inter alia on prudential supervision and reorganisation of financial institutions. Special attention shall be payed to the idiosyncratic aspects of the corporate governance of financial institutions. The respective research initiatives are embedded in the interdisciplinary center Sustainable Architecture for Finance in Europe (SAFE) and the Institute for Monetary and Financial Stability (IMFS). In contract law, the incentive effects of legal remedies for breach of contract constitute a major focal point of the Chair's scholarship. Moreover, the important impact of default rules and their judicial interpretation is considered with a special view to the background of the dynamic development in European Private Law. 

With respect to legal theory, the research methodology and the normative benchmark employed in the analysis of both existing and evolving corporate and contract law raises the question in how far an efficiency-oriented approach to law is legitimate and adequate.

In line with the research profile of the chair, I supervise dissertations in the areas of private and business law that I represent in my scholarly work. Potential topics for Ph.D.-theses must promise a fundamental and innovative contribution to scholarship in their field. I welcome comparative and interdisciplinary research approaches, particularly those situated at the intersection of law and economics (Economic Analysis of Law).

To ensure the adequate supervision of doctoral students, I generally confine the acceptance of Ph.D.-candidates to those who achieved results significantly above-average in the First State Examination or their comparable foreign law degrees. Applicants I do not know in person yet should have an articulate idea of a potential dissertation topic. In all cases, applicants will have to make sure to meet the general requirements for admission to doctoral studies at the Department of Law at Goethe University.

If you contemplate writing a dissertation under my supervision, your written application should not only include the usual documents (CV, photo-copies of diplomas, transcripts etc.) but also an outline of your research interests and your motivation for seeking to pursue them under my supervision.

The final acceptance as a Ph.D.-candidate will occur on the basis of a seminar-presentation of the contemplated research topic of the doctoral thesis or a comparably detailed research proposal.
