My main research interests are in genital and urinary cancers, and I lead a spectrum of clinical studies from phase I to randomised phase III. The majority of the studies are translational phase II studies investigating novel targeted and immune therapies.

I am the lead for solid tumor research at Barts Cancer Institute. I also lead the genitourinary (GU) cancer group at BCI.
My work focuses on a spectrum of clinical studies from phase I to randomised phase III. The majority of the studies are translational phase II studies investigating novel targeted and immune therapies. They exploit functional imaging and tissue collection.
Alongside these trials, our research focuses on correlation of novel biomarkers and aims to define markers that are of prognostic value and can predict response or resistance to therapy.
I have written over 100 peer review papers in this area and have grant income from national and international funding bodies.
I am on the editorial board of a number of journals and am part of the faculty for the major global oncology meetings.

I qualified from St Bartholomew’s Medical School in 1996 and trained in medical oncology at Imperial College. I completed post-graduate training in oncology in 2005 and received an MD from the University of London in 2006. My thesis was in mechanisms of resistance to therapy in urology cancers.
