Nina is a PhD student at the University of Bristol MRC Integrative Epidemiology Unit who is interested in the application of data science to social issues. Her PhD considers mental health inference from social media, particularly working on establishing high quality ground truth data sources from longitudinal cohort studies. Her research is a mixture of applied data science and qualitative work on the ethics of data linkage. Before starting a PhD Nina spent several years in children's safeguarding working with parents and children who lived with the impacts of mental ill health.
