Dr Fiona Cousins

Dr Fiona Cousins is a post-doctoral researcher within the Endometrial Stem Cells Group at Hudson Institute. She is researching the role of stem/progenitor cells in the repair and regeneration of the endometrium and in the pathology of endometrial diseases including endometriosis.

Her research projects are focused on finding a role for stem/progenitor cells in the regenerating endometrium, and investigating the requirement for Notch and Hedgehog signalling in the endometrial stem/progenitor populations that cause endometriosis.

After completing a Bachelor of Science (Hons) in Reproductive Biology in 2007 at The University of Edinburgh, Dr Cousins worked for bio-manufacturer Alba Bioscience (Quotient) before pursuing a Master of Science degree in Biomedical Sciences at Edinburgh Napier University in 2009.

From 2010-2014, Dr Cousins completed her PhD under the supervision of Professors Philippa Saunders and Hilary Critchley at The University of Edinburgh. Her project focused on delineating the mechanisms that contribute to the restoration of endometrial integrity following menstruation. During her PhD, Dr Cousins was also part of a group that developed an animal model for the study of endometriosis, closely mimicking the human disease. Dr Cousins undertook her first post-doctoral position with Professor Saunders from 2014-2015, exploring the inflammatory environment of the endometrium during post-menstrual repair.

In 2015 Dr Cousins was recruited to The Ritchie Centre under the supervision of Associate Professor Caroline Gargett to continue her work on endometrial regeneration. Dr Cousins’ main research interests are in endometrial function and dysfunction and how the latter may contribute to endometrial pathologies including endometriosis, adenomyosis or heavy menstrual bleeding.
