Professional background

I was appointed as a consultant at UCLH in 2007 with an interest in haemostasis and thrombosis. I am clinical lead for TTP and associated TMAs, including aHUS. I am also the clinical lead for ITP. We are a specialist centre for TTP and ITP.

Research interests

Research interests include TTP, aHUS and ITP.
