Here you find a short overview of our lecturers at the FFA:

Christopher Bisping, LL.M./Lawyer

Christopher Bisping, lawyer, is an associate professor at Warwick School of Law. Prior to that, he has taught at the University of Leicester for several years as well as at Warwick School of Law. Christopher Bisping has worked as a researcher at the Max-Planck-Institute for foreign and international private law in Hamburg and he was a member of the “Study Group on a European Civil Code”.

Christopher Bisping is a member of our FFA-Team since 2012. He is responsible for the course “English Vocabulary for Law: Legal Research” in our first semester.

“As a German jurist who is teaching and doing research abroad, I want to give future jurists the opportunity to gain first experiences in the dealing with foreign law. Moreover, to think “outside the box” contributes to a better understanding of the own system. The collaboration with the highly-motivated students of the FFA is great fun to me and it surprises me every time to see the progress that the students achieve in a short period of time.”
