My name is Dörthe Seidel. I studied medicine at the Universities of Rostock and RWTH Aachen and am a licensed physician. I worked for 13 years at the University of Witten/Herdecke in the Division of Clinical Research at the Institute for Research in Operative Medicine in Cologne.

From conception to publication, I was Principle Coordinating Investigator of a German-national and an international randomized clinical trial on the effectiveness and safety of a treatment method with an innovative medical device. In addition, I have accompanied many other study projects as Head of Department. Furthermore, I have been working for many years as a consultant in the field of evidence-based medicine for international companies in the medical device industry, preparing evidence analyses, assisting with applications and planning studies. In my practical work in the field of clinical trials, I have learned a lot, made many mistakes and, over time, understood many interrelationships. I would like to share this knowledge.
