As a clinically-trained academic in public health and infectious disease epidemiology, my research career has focussed on areas of public health priority: Tuberculosis (TB), HIV/AIDS, TB/HIV coinfection, sexual health and STIs. I have developed a cohesive programme of work that involves description and analysis of patterns of infections and associated risk factors in populations; molecular epidemiology; eSexual Health; and the development and evaluation of complex interventions. I am internationally–recognised for leading teams that produce innovative research that: (1) has clinical, public health and policy relevance; (2) links behaviour and biology; (3) combines infectious disease epidemiology with other disciplines; (4) spans developed and developing countries; (5) is both methodological and applied.
