Teaching

The modules offered meet the increased importance of international accounting regulations in companies. The modules are adapted to the study progress and build on one another. In cooperation with representatives of the business community, modules in Accounting and Auditing are offered in the bachelor's and master’s degree. In addition, external partners give guest lectures in various other modules. In-depth courses in seminar form are designed to encourage students to work independently on scientific issues. By offering courses in English, we prepare students for challenges in their professional life. Moreover, we offer various opportunities to exchange students that decide to study at the Faculty of Business Administration and Economics.

If you would like to write your thesis with us, you should have very good knowledge of external accounting and an interest in empirical research in accounting.

Theses are assigned via a central, web-based registration procedure of the Faculty of Business and Economics. If you would like to write a thesis with Prof. Kosi and her team in the form of a Bachelor's or Master's thesis, you can find the relevant requirements as well as registration deadlines and registration forms here.

A letter of motivation is not required for your application.
