- Personal history
Clinical: I qualified from St George’s Hospital Medical School in 1982 and spent the next 10 years working as a Physician with an interest in Diabetes in Endocrinology. I completed my PhD in 1993 and accredited in General Medicine, Endocrinology and Diabetes in 1992 and was about to take up a post as a Senior Lecturer, Consultant Endocrinologist in Bristol when I saw the light and became an SHO in Obstetrics and Gynaecology in the Westminster Hospital just before it closed its doors, moving to the brand new Chelsea and Westminster Hospital when it opened in 1993. In the next 6 years, I trained in Obstetrics and Gynaecology and set up the IVF unit in Chelsea and Westminster. The IVF unit was predicted to fail with in 6 months, but actually was highly successful, achieving a 28.5% (75 of 263 cycles, 9th in the UK) clinical pregnancy rate per treatment cycle for women under 38 years of age and for women over 38, 31.5% (121 of 384 cycles, 3rd in the UK). I accredited in Obstetrics and Gynaecology in 1999 and took up my post as a Senior Lecturer, Consultant in Obstetrics and Obstetric Medicine in 1999, becoming a Reader in January 2006 and then a Professor in Clinical Obstetrics at Imperial College, based at Chelsea and Westminster Hospital in 2010.
Research: My early research work (1986-1989) reflected the interests of my first mentor Professor Stafford Lightman and focused on the neuroendocrinology of the posterior pituitary. In 1989, I was awarded the William’s Fellowship by the University of London to study the role of the hormone Relaxin in reproduction. For the next 4 years Relaxin became my “raison d’etre”, finally influencing me to move from Endocrinology into Obstetrics and Gynaecology in 1993. I wrote my thesis while an SHO and was awarded my PhD in 1996. I then moved my interest into pregnancy and parturition, under the guidance of Professor Philip Steer before moving firmly into preterm labour in 2001 with the award of a grant from Wellbeing to study the role of Mechanical Stretch in Preterm Labour. Since then I have worked closely with Professor Philip Bennett, holding several grants together and co-supervising several PhD students.
Professor Philip Steer, my predecessor, retired in 2010 after a highly successful career in Academic Obstetrics and Gynaecology. He built up a large clinic in Cardiac Disease in Pregnancy and I have continued with his work in this area. Supervising 2 MD students and writing several papers, chapters and editorials.
I have supervised 10 higher degree students to date, 5 being awarded their degrees in the last 12 months. Currently, I have 10 higher degree students and work with 4 post-doctoral scientists and one Senior Lecturer Miss Vasso Terzidou.
- Research interests:
Heart disease in pregnancy
- Main research objectives:
Identify treatment modalities that will prevent or reduce the risk of preterm labour and its inflammatory consequences in the fetus.
Understand how the maternal immune system contributes to the onset of preterm labour.
Understand how pregnancy influences the progress of pre-existing heart disease and define the optimal management strategies for these complex cases.
