My main research interests are in ageing, primary care epidemiology and trials of complex interventions in primary care and community settings. This includes both epidemiological studies and complex interventions in the fields of health and well-being for older people, disease risk/prevention, mental health and health inequalities. Many of these studies involve the analysis of routinely collected primary health care data. Current examples include developing and testing complex interventions to promote well-being in later life in primary care and community settings (funded by MRC LLHW and the NIHR), an NIHR Programme grant to develop and test assertive management of cardio-vascular disease risk in people with severe mental illnesses and I am the UCL lead for the 'Ageing Well' programme in the NIHR School of Public Health Research.  I am a clinical adviser for the NIHR Research Design Service London and the Royal College of General Practitioners, and a Trialist with PRIMENT UK-CRC Registered Clinical Trials Unit, which specialises in trials of complex interventions in primary care and mental health settings. In addition to my research I am a practicing General Practitioner in North London.
