Personal profile
Research interests
I am a research fellow in Medical Statistics within the MRC Integrative Epidemiology Unit. My main research interests are longitudinal modelling in life-course epidemiology, analysis in the presence of missing data, causal inference, instrumental variable analysis, longitudinal modelling of disease biomarkers, analysis in the presence of non-random selection into a study, and clinical epidemiology of HIV and AIDS in the era of antiretroviral therapy.
My research aspirations are to work at the interface of methodological development and application. I enjoy explaining complex statistical methods and interpreting their results to other researchers, evaluating and comparing statistical methods using simulation studies in real-world contexts, and providing user-friendly software to implement statistical methods unavailable to non-specialist researchers.
