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 Health Data & Evidence Network (EHDEN) aims to answer research questions based on large data sets distributed across Europe while preserving the anonymity of patients. With support from EHDEN, the Charité is building an infrastructure based on the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) and the associated tools of the Observational Health Data Sciences and Informatics (OHDSI) program to make health data accessible for research in a structured form.

Further information

ORCHESTRA is a large-scale research project aimed at combating the coronavirus pandemic. The aim is to establish an international cohort for conducting retrospective and prospective studies in order to generate rigorous evidence to improve the prevention and treatment of COVID-19 and to be better prepared for future pandemics.

Further information

The partner sites of the HiGHmed consortium in the German Medical Informatics Initiative (MII) establish Medical Data Integration Centers (MeDICs), which integrate and harmonize data from healthcare and research systems. Important tasks include ensuring data quality and data protection to enable data sharing using the MII infrastructure. The added value of the solutions established will be demonstrated in various clinical and research use cases. 

Further information

In CODEX+ the collaborative research infrastructure CODEX of the Network University Medicine (NUM) will be rolled out more broadly and developed further, with a focus on new data sources, common data models, data anonymisation and convergence with the structures of the Medical Informatics Initiative and further NUM projects. 

Further information

The project "National Research Data Platform" (CODEX) of the Research Network of University Medicine on COVID-19 (NUM) aims to establish a secure and interoperable national data platform for research on SARS-CoV-2 and COVID-19. This will foster research on the current and future pandemics, as scientists from a wide range of disciplines will be able to quickly access a large number of standardized datasets. 

Further information

The Medical Informatics Initiative’s (MII) “Collaboration on Rare Diseases” (CORD_MI) aims to improve healthcare and research in the area of rare diseases. To achieve these goals, the technical as well as organizational solutions of the four consortia of the MII (DIFUTURE, HiGHmed, MIRACUM, SMITH) are utilized to share data on a nationwide scale. 

Further information

The H2O project brings together more than 23 partners with the aim to improve the quality of care for patients by creating health outcomes observatories that will collect standardised health data in an ethical and a socially responsible way. National observatories will be federated to create a pan-European network for health outcomes data with the purpose of engaging patients and connecting providers, ultimately equipping different stakeholders with the necessary data to improve patient care.

Further information

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.

Prior Projects

At TU Munich: Technical coordinator of the consortium Data Integration for Future Medicine (DIFUTURE), which is funded under the "Medical Informatics" funding scheme of the German Federal Ministry of Education and Research (BMBF). DIFUTURE aims at data harmonization and integration, as well as secure data sharing.

Further Information.

At TU Munich: Co-PI of the subproject „Secure integrated big data analytics“ building a central platform for the secure collection and processing of clinical, para-clinical and experimental data for the Collaborative Research Centre (CRC) 1371.
