Professional profile

I am based at Queen Charlottes Hospital, part of Imperial College NHS trust. My area of special interest is the management of early pregnancy complications (PUL, miscarriage, ectopic pregnancy), rapid access cancer diagnosis - and in particular the assessment of ovarian pathology, acute gynaecology and gynaecological ultrasonography. I have a specific role to drive research related to early pregnancy management and gynaecological ultrasound and have an H-index of 36. I am on the steering committee of both the IOTA and IETA trials - which are large international trials aiming to enhance the diagnosis of endometrial and ovarian cancer. I currently supervise 5 research fellows. I am registered to practice in Belgium and work in Belgium regularly where I am involved in the gynaecological scanning research team with Professor Dirk Timmerman.
In the private sector I work mainly at Parkside Hospital in Wimbledon and at the Women's Ultrasound Centre at 86 Harley Street in London. I provide a gynaecological ultrasound and early pregnancy assessment service on both sites. The clinic in Harley Street also deals with all aspects of obstetric ultrasound including fetal medicine, nuchal scans and invasive procedures.

Research interests

My research has been based around the use of ultrasound to study the morphology and vascularity of the female pelvis. Initially my interest focussed on the use of ultrasound and tumour markers to screen for ovarian cancer, but this quickly widened to the broader aspects of assessing many other forms of ovarian and tubal pathology. This culminated in the setting up of the International Ovarian Tumor Analysis (IOTA), a major multicentre trial examining the optimal diagnostic approach to adnexal pathology in general and ovarian cancer in particular. I have always felt that ultrasound and colour Doppler can be used to evaluate uterine and ovarian physiology and this has led to a number of studies of normal physiology. In recent years my work has also concentrated on the evaluation of early pregnancy. In particular this has involved the development of approaches to the characterisation of pregnancies of unknown location and the diagnosis of ectopic pregnancy. I feel that the study of pregnancy will inevitably look more closely at the first trimester. My current research programme is examining factors that influence embryonic growth in the first trimester of pregnancy.

Summary of recent publications

I have an H-index of 45. My current research interests relate to the management of early pregnancy complications, the diagnosis of miscarriage, early pregnancy embryonic growth and serum biochemistry, characterising endometrial pathology, psychology of pregnancy loss, pregnancy implantation, caesarean section scars, the diagnosis of ovarian cancer and the characterization of ovarian pathology.

Personal profile

I have always been a keen sportsman. Having played league cricket for some years, I am a member of the MCC and Ditchling cricket clubs. Previously I have played a significant amount of rugby and now spectate at Gloucester rugby club. I still train regularly and take part in triathlons each year. I sail when I have time, and am a member of Bembridge and Royal Solent sailing clubs.
If I have the time I enjoy the theatre and cinema. I used to paint oils and watercolours but have little time for this at present. In the last few years I have taken up drumming again after a gap of decades.
