Further advancing digital medicine requires innovative solutions for integrating healthcare and medical research data. From the perspective of medical informatics, there are important open questions. How can the required collection, integration and analysis of large and heterogeneous data sets be achieved in an efficient, effective and scalable manner? How can the trust of citizens and patients be maintained in the context of rapid change? These and related questions define the research profile of the group.

We focus on four key areas: (1) technologies for interconnecting health data and for patient participation, (2) information integration and big data architectures in translational medicine, (3) cross-site data analysis and data sharing, (4) information security and data protection in digital medicine.

Our group conducts application-oriented research to create added value for health care and medical research, as well as basic research to develop novel methods with which the underlying challenges can be tackled more effectively.

Current Research Areas

  • Pay-as-you-go integration systems for health data
  • Scalable information infrastructures for medical research projects
  • Clinical and translational data warehousing
  • Data harmonization and semantic integration
  • Methods and tools for applying privacy-enhancing technologies, such as anonymization and pseudonymization, in medicine
  • Secure distributed computing in healthcare

Current Projects

The European Joint Programme on Rare Diseases (EJP RD) brings together over 130 institutions from 35 countries to create a comprehensive, sustainable ecosystem for research, care and medical innovation in the area of rare diseases. In the project, the BIH Medical Informatics Group works on tools and methods supporting sustainable data sharing with a specific focus on privacy aspects.

Further information

The National Research Data Infrastructure (NFDI) will systematically catalog, sustainably maintain and make databases from science and research accessible and interconnect them (inter)nationally. In this context, the goals of NFDI4Health include (1) enabling the findability of and the accessibility to structured health data, (2) establishing and improving the interoperability and reusability of health data and (3) enabling the sharing and linkage of health data while complying with data protection requirements.

Further information

The Lean European Open Survey on SARS-CoV-2 (LEOSS) is a European non-interventional prospective cohort study on the epidemiology and clinical course of SARS-COV-2 infections. The objective is to further develop evidence-based diagnostic and therapeutic recommendations. Our group contributes to this project by developing and implementing multiple layers of safeguards to support privacy-preserving data sharing.

Further information

ARX is a comprehensive open source software for anonymizing health data. It supports a wide variety of risk models, data transformation techniques and methods for analyzing the usefulness of output data. The software has been used in a variety of contexts, including commercial big data analytics platforms, research projects, clinical trial data sharing and for training purposes. ARX is able to handle large datasets on commodity hardware and it features an intuitive cross-platform graphical user interface.
