About Me

I'm a technology, copyright and data protection lawyer. My ambition is to provide the best and most suitable advice to clients and, in particular, to guide them through their technology transactions, IT and data projects in a pragmatic, solution-driven and innovative manner.

As co-head of our international Technology & Communications Group and head of our German Data Protection Group, I divide my time between our Frankfurt and Düsseldorf offices. I specialise in technology, digital media, cloud computing, copyright and data protection law and advise providers and customers in technology transactions, IT projects, data protection matters and copyright issues. I also draft and negotiate complex commercial contracts, and advise on IT law as well as on contractual and regulatory issues of digitalisation and cyber security. I particularly focus on issues arising from the use of new technologies and business models, such as cloud and data driven projects, IoT, AI and machine learning, and other issues of the digital transformation.

I'm recommended by the leading directories (such as Chambers, JUVE, LEGAL500, MIP and Who's Who Legal) for my expertise in technology, data protection and copyright law. Legal 500 Germany list me as one of the six (2018) and nine (2019) leading data protection lawyers in Germany.

In addition to my work as an editor of the Cloud Computing Legal Guidebook "Niemann/Paul", I often speak and am interviewed on technology, cloud, digital transformation, data protection and copyright topics.
