Dr. Christa Tobler is professor of European Union law at the Europa Institutes of the Universities of Basel (Switzerland) and Leiden (The Netherlands). In her research work, Prof. Tobler puts a particular emphasis on the concepts of legal equality and discrimination, both in economic and in social law. Prof. Tobler's second field of specialisation concerns the legal relationship between the European Union and Switzerland (i.e. the so-called „Switzerland model“ that is also discussed in the context of „Brexit“). Prof. Tobler has created a Massive Open Online Course (MOOC) on this subject for the University of Basel, which is freely available („Switzerland in Europe: Money, Migration and Other Difficult Matters“, https://www.futurelearn.com/courses/switzerland-europe ). On the level of teaching, Prof. Tobler is part of the Eur-Charts Project, which provides a new teaching tool for the field of EU law aiming at visualising EU law.
