Katharina A. Weimer, LL.M. (UNSW)

My main areas of practice
As a data protection expert, I help my clients to find their way through the German and European legal jungle and to find solutions for their scientific and commercial proposals for data marketing.

My focus on the connection between Life Sciences and Data Protection is related to a plethora of complex questions about the collection and use of sensitive data.

National and international companies entrust me with the structure and roll-out of their GDPR projects and engage me as a consultant on e-commerce websites and data flows, on personal data of employees and on the creation of consent forms for clinical trials.

I not only help on the data protection side, but also deal with the underlying commercial contracts and structures on a daily basis.

Since every sector has to comply with the regulatory requirements in equal measure, my clients come from all sectors. However, a certain focus - obvious due to my practice - is on Healthcare and IT. From start-ups in the field of social media marketing to established pharmaceutical companies, my services are used as a trusted advisor.

For a medical device manufacturer, I act as European legal counsel on almost all legal issues, including reimbursement strategies as well as health advertising, competition advice and research collaborations.

I advise my clients in German and English.
