As a joint PhD between Normandie Universite Rouen and the University of Helsinki, Marta’s Examination was be conducted by:
Custos : Prof Kurt Fagerstedt, University of Helsinki (Finland).
President: Prof Matty Berg, Vrije Universiteit Amsterdam (The Netherlands).
To meet the requirements of the co-tutelle PhD, the defence commenced with a 50 minute presentation – followed by 20-30 minutes of questioning by each examiner in turn.
