I) Haemostasis and thrombosis:

1.Research into recurrent miscarriage: this includes research into the underlying causes and the potential association with prothrombotic states and the influence of antithrombotic intervention. I led on the laboratory services, which ensured the delivery of the thrombophilia testing for the recurrent miscarriage services at St Mary’s Hospital. The work was published in several papers, which supported the genesis of national and international guidelines:

2.Prevention of VTE: major interest in the VTE prevention strategies. I led on research and published data on how to improve uptake of VTE prevention on medical patients. This work contributed locally and nationally on VTE guidelines and attracted a massive response in the medical community and the media including a BBC news interview by the scientific editor. I later contributed significantly into local guidelines and was instrumental in the planning for, delivery, and implementation of DoH CQUIN VTE prevention initiative. I led on publishing this experience.

3.Novel therapeutic approaches in Stroke

Contributed to the studying the use of CD-34 haemopoietic stem cells by arranging and ensuring aseptic technique in collection of bone marrows from patients in the study. This was first in humans study. The paper was short-listed for the The STEM CELLS Translational Medicine Young Investigator Award honors
