23.12.2021: Dr.-Ing. Cornelia Kalender appointed President of Windtechnologische Gesellschaft Deutschland: An Interview

Dr.-Ing Cornelia Kalender studied environmental engineering and resource management at the RUB, but only came into contact with the topic of wind during her studies as part of her diploma thesis supervised by Prof.-Dr.-Ing. Höffer, owner of the Wind Engineering and Fluid Mechanics working group. As a student assistant at Niemann Ingenieure working under Prof. Höffer's predecessor em. Prof. Hans-Jürgen Niemann, she was involved in a wide variety of engineering projects at an early stage, including wind tunnel measurements. Hooked by the topic, she started working as a research assistant for Prof. Höffer in spring 2008. In 2014, she received her doctorate on the topic of „Windinduzierter Partikeltransport – Synergetische Kombination von physikalischer und numerischer Simulation“. As a Post Doc at the working group, she continues to work in the areas of computational fluid dynamics and wind tunnel experiments for wind flows in the built environment. In November, she was appointed president of the Windtechnologische Gesellschaft Deutschland, a welcome occasion to talk to Dr.-Ing Cornelia Kalender in more detail.
