Currently I am working on the data-privacy related PRIVASA project and the HCT 2.0 project.

My research focus is on data privacy-preserving learning techniques in life sciences, machine learning methods and federated learning techniques. Additionally I work with data harmonization and federation in medicine, such as the OMOP Common data model.

Data analytics courses teaching assistant.
