PhD Thesis

I am currently working on finishing my PhD Thesis at Media Use Research Group at University of Hohenheim, Stuttgart. In the thesis I am researching on the potential of virtual reality in the context social science studies. In more detail, I evaluate the (external)validity of studies done in VR and their potential to be transferred to the real world. My supervisors are Prof. Dr. Vogelgesang (University of Hohenheim) and Prof. Dr. Matthias Wölfel (Karlsruhe University of Applied Sciences) and Ass.-Prof. Dr. Tobias Dienlin (University of Vienna) has agreed on mentoring me.
