Dr. rer. nat. Oliver Karras
Postdoctoral Researcher & Data Scientist & Lecturer

I am a post-doctoral researcher, data scientist, and lecturer working at the Data Science and Digital Libraries Research Group at TIB – Leibniz Information Centre for Science and Technology. I hold a Bachelor of Science and a Master of Science degree, as well as a Ph.D. in Computer Science from Leibniz Universität Hannover. Furthermore, I am involved in the research projects Open Research Knowledge Graph (ORKG), National Research Data Infrastructure for Engineering Sciences (NFDI-4Ing) consortium, which is part of the National Research Data Infrastructure (NFDI), and FAIR Data Spaces (FAIR-DS). As part of this work, my research addresses the development of the Open Research Knowledge Graph for application to engineering science. The focus is on the formalization, discoverability, and accessibility of methodological knowledge and information on semantically rich and machine-interpretable concepts for engineering problems.

I am a member of the Gesellschaft für Informatik e.V. (GI), deputy spokesperson of the Fachgruppe Requirements Engineering (RE), and a regular reviewer and member of various program and organizing committees of conferences and journals.

Before joining TIB – Leibniz Information Centre for Science and Technology, I was a research assistant and Ph.D. student at the Software Engineering Group at Leibniz Universität Hannover. I worked as project leader of the DFG research project ViViReq and researched the integration of videos as a complementary communication medium in requirements engineering. My research focused on supporting requirements communication between stakeholders and the development team to foster the development of a shared understanding of the project vision of the system under development among all project partners involved. I have published my research in over 40 national and international publications covering diverse topics such as requirements engineering, social software engineering, machine learning, and natural language processing.
