David joined the Unit in 1998 after previous spells at London School of Hygiene and Tropical Medicine and the Institute of Child Health. In 1997 he gained a PhD on statistical issues around the vertical transmission of HIV infection.
His main current research interest is HIV drug resistance. He is the co-PI of the UK HIV Drug Resistance Database (UKHDRD), which aims to collect all resistance tests performed as part of routine clinical care in the UK and to link these to key clinical/demographic data. He has a particular interest in the epidemiology of transmitted drug resistance and UKHDRD has provided several important insights on this topic.
A more recent development is collaborating with Dr Sheena McCormack to design and implement a pragmatic randomised controlled trial to assess the effectiveness of pre-exposure prophylaxis to reduce the risk of HIV transmission among gay men in the UK. Although the biological efficacy of this intervention has been clearly established, its "real-life" population effectiveness has not.
David remains interested in statistical methodology that is motivated by practical applications. With colleagues he is currently working on unbiased estimation of linear mixed models where data are both right- and left-censored.
David is the Lead for the Statistical Group, representing the 40 or so statisticians in the Unit.
