On 1st July 2018, I joined Riegler-Klar & Partner Pharma-Consulting GbR as a managing director. I have several years’ experience as Regulatory Affairs Manager at Brinker Pharma GmbH (later Xendo Deutschland GmbH) where in addition to the preparation of the clinical documentation for registration dossiers, I was responsible for the supervision of marketing authorisation procedures. Before joining the area of drug regulatory affairs, I worked in drug development. My focus is on both the preparation of the clinical documentation for pharmaceuticals (clinical dossiers) and the product information.
