Clinical Skills

During subspecialist training at UCLH I had the opportunity to work with and learn from international experts in the field of reproductive medicine. Beyond the subspecialist curriculum I gained experience in fertility preservation for cancer patients as well as the management of fertility aspects of complex medical disorders. Training at UCLH has helped me develop advanced surgical skills in laparoscopy and hysteroscopy performing several such operations independently during my locum appointment. As a locum consultant I worked with my colleagues to expand services within the reproductive medicine unit and helped increase surgical activity within the gynaecology department.

I have extensive experience in gynaecological and early pregnancy ultrasound with several publications and book chapters in the field. This background has enabled me to assume primary responsibility for ultrasound service provision in the Reproductive Medicine Unit where we strive to provide patients excellent diagnostic care. My scanning skill extends to my other roles as a consultant in acute gynaecology and in training of junior doctors. Apart from providing direct clinical care I have been active in training and supervision of the 4 research and clinical fellows in the unit. I am certified as educational supervisor.

Academic Experience - Research

Throughout my career I have focused on the academic aspect of the specialty. I have initiated, developed and followed through to publication several projects. Some of the publications have had significant impact, becoming part of national guidance.

During my lectureship I started an innovative project to identify non – invasive biomarkers of endometriosis which supported a successful PhD candidate. I am local principal investigator for PRE – EMT, a national trial for the post - operative management of endometriosis.

I have contributed to 28 peer reviewed publications including 11 first author papers and 5 book chapters. I regularly present at National and International conferences.

Academic Experience - Teaching

As a clinical lecturer and then as consultant I have regularly taught medical students in large groups and in tutorial format. I teach on two reproductive medicine MSc courses and have supervised a successful student dissertation. I am personal tutor for 4 fourth year medical students.

I participate in postgraduate teaching both at the Royal College, where I regularly teach early pregnancy and intermediate gynaecological ultrasound and in the Deanery, where I teach on the laparoscopic surgery course.

I facilitate the London Deanery hands-on laparoscopic and hysteroscopic course held at UCLH every year.

Management and Leadership Skills

As part of leadership training I initiated a quality improvement project to develop of a one – stop fertility assessment service. I cooperated with hospital management to develop, cost and initiate the service as a pilot and then as a regular clinic. Within the last 6 months we have seen over 130 couples to acclaim from patients and colleagues streamlining clinical service and improving patient experience.

During my time as consultant in the reproductive medicine unit at UCLH I have actively participated in and contributed to plans to increase the unit’s activity. Through our collective effort we have been successful in meeting our current targets.

I currently have primary responsibility for overall scheduling in the unit which includes coordinating with the unit’s management to allocate staff to clinics and ensure the most efficient use of resources in terms of personnel, space and equipment.

I manage the schedule of 4 research fellows to ensure their educational needs are met and balanced with the needs for service provision. I have participated in interviews for the appointment of new staff. Our unit enjoys high reputation amongst trainees as a friendly and educationally excellent clinic and we have good staff retention.
