Catharine Hof studied architecture at the Karlsruher Institut für Technologie. 1998 she received a PhD with a work on wood constructions from the 16th tot he 18th century in the voivodship Waldenburg. Following this she has held research positions in Karlsruhe and was public relations and data processing officer at Zeppelin Museum Friedrichshafen and Deutsches Archäologisches Institut in Berlin where she is also member of several research projects that are settled in Sudan, Syria, Ethiopia and Italy. Her research focuses on historical construction research and documentation, culture and technology transfers as well as reconstructions, visualisations and animations. While researching at Topoi she works together with research project (B-2-7) Resafa by investigating the water management infrastructure of ancient Resafa. As the natural ground water was undrinkable the city of ancient Resafa had to rely on rainwater that was saved in a big cistern. Catharine Hofs contribution to this investigation is to analyse raw data material in order to design a 3D-model of this big infrastructure monument to make stratigraphic relations visible.
