Professional background

I qualified from St Bartholomew's Hospital, London with surgical training in Cambridge and urological specialist training in London. I have been a Consultant at UCLH since 2001 although only formally appointed in 2004. My specialist interests are medical and surgical treatments for the penis and male factor infertility. This includes microsurgery techniques up to major free flap penile reconstructions. I am part of the tertiary andrology referral service at UCLH. Erectile dysfunction and Peyronie's surgery also comprises a large component and this includes penile prosthesis surgery.

Research interests

Erectile dysfunction, male factor infertility, penile reconstruction.
