Marleen has been bouncing around between European countries and different disciplines, completing a degree in Architecture at the Technical University of Wuppertal, Germany, a degree in Heritage Science at Queen’s University, Belfast, Northern Ireland and a Marie Sklodowska Curie Fellowship in Digital Cultural Heritage in Vienna, Austria. She’s now working toward a PhD in History at the University of Luxembourg, where she is doing virtual reconstructions of castles.
