Professional background

My main areas of practice
I have more than 25 years of experience in these areas and advise my clients in all legal areas covered by IT and digitalisation, in particular in international Data Protection Law and in the area of data economy, IT contract law as well as in legal issues relating to Cybersecurity, IT Security and E-commerce.

My clients include technology companies, the public sector and, in particular, international life science companies. My advice covers legal issues in connection with digitalisation processes and the establishment of data rooms and data sharing as well as the use of new technologies such as Artificial Intelligence, Blockchain and Big Data.

I am constantly involved with current developments in the constantly changing regulatory framework of the Internet and Technology sector in Germany and Europe.

Among other things, I recently advised the German Federal Ministry of Economics and Technology on the development of the European cloud and data project "Gaia-X".

I advise my clients in German and English.
