In 2014 he was Members of the AIUM consensus group on diagnosing ovarian canceralso a member of the  American Institute of Ultrasound in Medicine (AIUM) consensus group to develop new guidelines for the classification and management of ovarian cysts and the diagnosis of ovarian cancer.

He is also PI for the EPOS trial on the impact of early pregnancy events, ABPEP on serum biomarkers in early pregnancy and PIEPE examining the psychological impact of early pregnancy complications. Professor Bourne can be seen speaking about the diagnosis of miscarriage trial - published in the BMJ and can be read by here. In Meeting of new Tommy's Centre management group2016 he became Director of Early Pregnancy Research at the new Tommy's National Centre for Miscarriage Research - a joint centre between Imperial College and the Universities of Birmingham and Warwick.

Giving the plenary lecture on the psychological impact of miscarriage at ISUOG SingaporeHe is a research team leader at Imperial College. His current research interests relate to miscarriage, the management and psychology of early pregnancy complications, early pregnancy embryonic growth, caesarean section scars, the diagnosis of ovarian cancer and the characterization of ovarian pathology. He has an interest in medical regulation and works with the BMA doctors for doctors service on the IMPACT study. He has ongoing collaborations with staff at the universities of Leuven, Birmingham, Buckingham, Edinburgh, Lund, Prague, Sydney and others.
