Biography

I am currently a Research Manager for the Centre Healthcare Randomised Trials (CHaRT), a fully registered UK Clinical Research Collaboration Clinical Trials Unit with an internationally recognised expertise in the design, conduct, analysis and reporting of multicentre trials.  I joined the Unit in 1993.  I completed my PhD in the Unit in 2002 and went on to take up a Wellcome Trust Training Fellowship in Health Services Research which I completed in 2006. I am a Health Services Researcher experienced in a range of HSR methods including systematic reviews, pragmatic RCTs (simple and complex), and other evaluative designs. I have previously worked on a series of "knowledge translation" evaluations ie getting evidence into clinical practice, involving complex rigorous designs.
