My current principal areas of research are:
prostate cancer aetiology (with a focus on metabolic factors such as the IGF system), predicting its progression and secondary and tertiary prevention of the disease via population-based screening and low-toxicity nutritional and lifestyle interventions;
the short- and long-term child and adult health effects of breastfeeding and early growth;
uncovering unexpected beneficial and adverse effects of commonly prescribed drugs through pharmaco-epidemiological studies based on automated clinical databases such as the UK GPRD.
