About my research

Since January 2017 I am a Ph.D. student at CISPA, Saarland University. I am working in Michael Backes' group on Health Privacy.

Today, biomedical research is fuelled by various data types measured from patients, which is quite costly to get at large scale. Therefore, data sharing is essential. Unfortunately, many data sharing systems designed by biomedical researchers are either threatening patients' privacy or too restrictive to be used at large scale.

Thus I try to find a middle ground. That means, I first explore the privacy risks of a system for publishing health-related data. Having found risks, I re-design the system such that it enables biomedical researchers to share their data in a privacy-preserving way. Concretely, I am currently working with these types of data:
