Denis Nagel

PhD in "People, Digital Intelligence and Recycling – Shaping Urban Life Together"

My name is Denis Nagel. I was born on the 20 September 1993 in Wittingen, Lower Saxony. After finishing High School at the Gymnasium Hankensbüttel in 2012, I started studying computer science at Technische Universität Braunschweig. There I developed a high interest in databases and information systems in general. After successfully finishing my bachelor thesis at the institute for information systems (IfIS) (2017) I took the opportunity to start working as student assistant in the research of the institute. This allowed me to get a first glimpse at the scientific work during my master studies. During this time I also had the chance to participate in a few scientific publications. After receiving my master degree at the end of 2019 I decided to stay in research and as such I am employed at IfIS as a scientific assistance since March of 2020.

Currently my work focuses on the topic of narrative intelligence. In times of big data it gets increasingly difficult to extract important information from ever increasing amounts of data, extracted from experiments, surveys or studies. I therefore try to answer the question how argumentations in the form of narrative structures are expressed in vast data collections and how we can identify them using automated approaches.
