My main areas of interest are cancer epidemiology and pharmacoepidemiology. I currently hold a Wellcome Trust/Royal Society Sir Henry Dale Fellowship for a programme of work looking at cardiovascular diseases among people with a history of cancer. I am also interested in mental health and quality of life among cancer survivors and am supervising a research degree student working on this topic.

I have an ongoing interest in pharmacoepidemiology, particularly in relation to cancer outcomes, and I recently completed an NIHR postdoctoral fellowship programme in this area. I have also studied other predictors of cancer risk, notably body mass index.

I have an ongoing interest in the use of eHealth data and am part of a wider group at LSHTM working with large-scale routinely collected data such as the Clinical Practice Research Datalink (CPRD) primary care data.

Finally, I am interested in the application of novel or non-standard statistical methods to real clinical problems: a current interest is whether marginal structural modelling and related methods can help to disentangle the effects of drugs from the effects of underlying disease in observational diabetes research, i.e. to tackle time-varying confounding by indication.
