Mark Hillen, Ph.D.


Mark has a Wellcome Trust 4-year Prize Scholarship PhD from the University of Edinburgh in Developmental Neurobiology, and a BSc (Hons) degree in Pharmacology from the University of Glasgow, Scotland.

Mark has over a decade’s worth of medical communications experience, first as an agency Medical Writer, facilitating the production of journal manuscripts (ranging from primary scientific data, clinical trials (Phase I-III) and review articles) and congress presentations, as well as business intelligence, literature analysis, competitor benchmarking and patient-focussed materials. His next move was into scientific publishing, as the Editor of The Ophthalmologist, launching the publication in 2013 and the North American edition in 2015, bringing his skills developed from, his academic and agency past to help make these titles successful. In 2018, Mark brought his skillset to Zurich to work for the ELZA Institute as Director of Communications.

As Director of Communications at ELZA, Dr. Hillen is involved in the development of most of the public-facing materials ELZA produces – from customised postage stamps and patient leaflets to review articles in scientific journals. Mark believes that both the clinical and research work performed at ELZA is, respectively, life-changing and incredibly important, and is proud to be able to help the ELZA team communicate their work clearly and effectively.


Mark Hillen, looking handsome.
