MEDICAL WRITER
Medical writer with strong analytical skills, linguistic precision, and the ability to translate complex scientific data into clear, publication-ready content.
ACADEMIC BACKGROUND
Biology degree at Technical University Braunschweig – completed in the Department of Cell Biology, with research on transgenic and cellular techniques in the zebrafish disease model. Various research projects and a pharmaceutical-biomedical environment sparked my interest in medical and scientific communication.

Alongside my work in medical writing, I bring experience as a freelance copywriter, composer, sound designer, and producer. Through my many years in the advertising industry, I have extensive experience collaborating with advertising agencies and in media production.
