My specialisation is in health inequalities, health economics evaluation, global health, and quantitative analytical research. For the past three decades, I have been actively involved in research issues relating to health and well-being. I undertook both national and international levels policy and advocacy research studies in the areas of public health and nutrition, population diversity in health, health inequalities, global health systems, healthcare financing and health economics evaluation. There were several studies which involved collection and handling of large quantitative complex data including clinical trials. I have considerable experience in managing and analysing large household surveys including longitudinal datasets using SPSS package.
