Postdoctoral Researcher in the area of Scientific Data Management and Knowledge Graphs (m/f/d)

As the German National Library of Science and Technology our future-oriented services ensure the infrastructural requirements for a high-quality supply of information and literature for research in science and industry. Our services as a university library secure the local supply for the Leibniz University Hannover.

The Technische Informationsbibliothek (TIB) – Leibniz Information Centre for Science and Technology – Program Area C, Research and Development, is looking to employ a

Postdoctoral Researcher in the area of Scientific Data Management and Knowledge Graphs (m/f/d)

to join the Scientific Data Management Group (Prof. Dr. Maria-Esther Vidal) at the earliest possible opportunity.

The position is initially limited to 3 years with envisioned extension. The regular weekly working time is 39.8 hours (full-time). The position is only suitable for part-time work to a limited extent. The remuneration is based on pay scale group 14 TV-L.

Your challenge
We are looking for an ambitious researcher aiming to build a successful track-record in science and technology in the context of knowledge graph technologies and contributing to strategic research and technology goals of TIB and the joint-lab with Leibniz University Hannover.

Research projects around the world produce a tide of data every day. The potential lies primarily in connecting the pieces of information and extends far beyond the individual project results. This position is part of a research project called “A Framework for Knowledge Graphs based on Semantic Integration, Representation and Curation of Scientific Data to enable Trustable and Interpretable Knowledge Exploration and Discovery (TrustKG)” funded by the Leibniz Association. The project TrustKG will develop computational methods for transforming biomedical data into semantically rich and linked knowledge graphs. These methods will enable interpretable large-scale data integration to empower Artificial Intelligence with semantic descriptions and transparency. The project will use these computational tools as building blocks for supporting individual treatment approaches in lung and breast cancer and for Covid-19 patients.

Your tasks will focus on
The candidate is expected to take a leading role in the research group and to conduct research closely together with Prof. (Univ. Simón Bolívar) Dr. Maria-Esther Vidal in the context of knowledge graphs and the TrustKG project. It is expected that you have experience in at least three of the following areas:

  • Publication of research results in renowned, peer-reviewed journals and conferences
  • Experience and interest in leading research teams
  • Proven software engineering skills and the ability to lead the development of mature software components beyond pure research prototypes
  • Successful supervision of bachelor, master and doctoral students
  • Collaboration with other research groups, industry, NGOs as well as open-source and community initiatives, for example in the context of publicly funded collaborative research projects
  • Successfully competing for funding by national, European and international funding bodies

Your qualities
The ideal candidate holds a doctoral degree in Computer Science, Information Science, Mathematics or a related field and is able to combine theoretical and practical aspects in his/her work. The candidate should have a strong background in a field relevant for Web and Data Science, such as:

  • Databases, query processing and data integration
  • Semantic technologies, linked data and ontology engineering
  • Knowledge graph creation and representation
  • Knowledge representation, logic databases and causality models
  • Natural language processing and information retrieval
  • Software engineering and modern application development

Fluent English communication skills are a fundamental requirement; command of the German language is a plus.
