Alex Gentry-Maharaj, Principal Research Fellow

Alex joined the Gynaecological Cancer Research Centre in 2003, initially based at Barts and since 2004 at UCL (Institute for Women’s Health). She has been an integral part and a Project Lead for one of the largest individually randomised controlled trials in the world, the United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS). Alex has contributed to all the publications resulting from the trial, both from the core work and secondary studies.

In 2005, with Prof Usha Menon, Alex set up and co-led the United Kingdom Ovarian cancer Population Study (UKOPS), one of the Ovarian Cancer Association Consortium studies contributing to the first ever Genome Wide Association Study for ovarian cancer.

In 2018, the UKCTOCS team moved to the MRC CTU at UCL where Alex continued her active roles. In 2021, she also took on Project Co-lead roles for the ICON8B and Add-Aspirin trials.

Alex is passionate about education and has since 2016 contributed to the design of a number of modules at both undergraduate and postgraduate level. She co-leads five modules across the Institute of Clinical Trials & Methodology and Institute for Women’s Health. Since 2022, Alex is the MSc Clinical Trials Programme Director.

Since 2022, Alex had taken on role of a CRUK International Alliance for Cancer Early Detection (ACED) Co-Director of Research Domain Trials and International HundredK+ Cohorts Consortium (IHCC) Steering Committee role.

Alex completed her PhD in molecular biology of cancer at King’s College London in 2002 following an MSc Medical Immunology at St. George’s Hospital Medical School.
