His PhD research related to the anthropology of political borders, with ethnographic focus on the border region between Italy, Slovenia and Croatia known as the “Julian Region”. He examined how cultural and national identities are constructed through conflicting collective memories in a political and cultural environment defined by historically changing borders. He wrote his PhD thesis as a narrative evolving from the life-stories of self-identified Italians from Istria who for various reasons chose to leave Tito's Yugoslavia and moved “back” to Italy.
After his PhD, Thomassen has engaged various areas of research. He writes and publishes on immigration in Italy. Together with colleagues James Walston and Isabella Clough-Marinaro he has organized several conferences on immigration and integration in Italy. In this context he is also engaged in various community projects, including a project launched by the American University of Rome in 2011 to foster immigrant leadership in Italy.
