What am I doing I provide peace and stability in hectic times and try to help clients regain their strength to do what they do best.
In addition to litigation, I advise clients on all aspects of IP and contract law, including establishing security rights, drafting (license) agreements and conducting due diligence. In the field of pharmaceuticals, I advise and litigate on matters such as advertising for (prescription) medicines, product liability, packaging, parallel imports, maximum prices and reimbursements.


I regularly give presentations and publish on the aforementioned areas of interest, including in the magazines IER and JGR.
