Clinical Trials

We are carrying out a number of research studies to help us design and test new treatments for cervical abnormalities caused by infection with oncogenic HPV.

HPV Vaccine Trial

REVEAL-01 is investigating the first therapeutic vaccine to show efficacy against cervical abnormalities associated with HPV-16 and HPV-18. Its predecessor trial was published in the Lancet in 2015, indicating the vaccine could present a non-surgical option to treat CIN2/3. REVEAL-01 is a randomised, double-blind, placebo-controlled study involving 200 sites worldwide.

HPV Immunity study

This trial aims to find out how the immune system clears high-risk HPV, the viruses that cause cervical cancer ( We are looking for women aged 16-24 years who are in good health. If you are interested, please contact the research team on

Biography & Research

I received my medical degree from the Humboldt-University of Berlin in 2003 and split my specialist training between the Charité - Universitätsmedizin Berlin, in Germany, and Oxford University Hospitals NHS Foundation Trust, in Oxford, UK.

I interrupted my clinical training and spent 4 years as a postdoctoral research fellow at Harvard Medical School / Brigham & Women's Hospital in Boston, USA, where I have been working on the molecular mechanisms of human papillomavirus (HPV) associated carcinogenesis and drug discovery strategies for cervical cancer.

In 2011, I joined the University of Oxford as a Clinical Lecturer and am part of Prof. Zondervan's and Prof. Becker's Endometriosis Care and Research (EndoCaRe) team. My laboratory work focuses on single cell transcriptomic profiling of healthy and diseased endometrium.

I have a strong clinical interest in HPV associated cervical disease and am leading a research programme in the field of the molecular basis and clinical managment of cervical dysplasia. I am the lead consultant for the colposcopy service in Oxford and Principal Investigator of multiple national and international clinical trials.

In addition, I am a board member of the British Society for Colposcopy and Cervical Pathology (BSCCP) representing the South-East of England, a BSCCP accredited colposcopy trainer and elected member of the Society for Reproductive Investigation (SRI). In my spare time I volunteer as expert reviewer for Jo's Cervical Cancer Trust Charity.
