Professor Ceran was, for many years, the director of the Department, then the Chair of Byzantine History, at the University of Łódź – the first, and largest, of such academic units in Poland. Throughout his long academic career, he held a number of roles, amongst which he was the director of the Institute of History, University of Łódź, as well as the president (subsequently honorary president) of the Commission of Byzantine Studies at the Committee of Ancient Culture, Polish Academy of Sciences (the Polish national committee of the Association Internationale des Études Byzantines). He began his studies as a student, and then became a close collaborator, of Professor Halina Evert-Kappesowa, the doyen of Byzantine studies in Łódź. He received substantial specialized training from such noted foreign scholars in the field such as Professor Paul Lemerle and Professor Nina V. Pigulevskaya.
Professor Ceran specialized in the history of Antioch during Late Antiquity, the relations between the Church and the Byzantine state as well as the history of the Mount Athos monasteries. He was an indefatigable propagator of ancient and medieval history (especially of the Byzantine Empire). Thus, the decision to name the newly founded Waldemar Ceran Research Centre for the History and Culture of the Mediterranean Area and South-East Europe after him seemed fitting to the founding members. The creation of the Ceraneum in a way fulfills the aspirations of Professor Ceran himself. He devoted all his life to developing the Byzantine studies community in Poland and popularizing the research on the history of the Eastern Roman Empire.
