Julia has been supporting the Structural Design & Mechanics group as a lecturer since September 2021 . Her special interests are in membrane and shell structures as well as in (sustainable) cellulosic building materials such as cardboard, wood and bamboo. 

Julia studied civil engineering at the Technical University Munich. Within her study she spent two semesters at the École Nationale des Ponts en Chaussées (ENPC) in Paris and did her master’s thesis at the University of Toronto in Canada. After completing her studies in 2002, Julia came to the Netherlands to start her PhD research at the Technical University of Delft. She joint the Structural Mechanics group of  Prof. Jan Rots at the faculty of Architecture. There she investigated and modelled the mechanical properties of paper and cardboard to be applied as structural building material. 

In 2009 Julia started her practical experience as structural engineer at the Dutch company Witteveen&Bos. There she was working for about 3 years on various civil engineering structures such as dikes, locks, weirs and bridges. Since Julia was always interested in more architectural structures she decided to make a switch and started to work at Tentech, an engineering firm that is specialized in lightweight and membrane structures. At Tentech Julia had the opportunity to work on structures for the event and architectural sector in a very international field. The projects were predominantly membrane and demountable lightweight structures, but also buildings made of special materials such as cardboard, timber (CLT), bamboo, mycelium and 3D printed composites.
