Before joining LSHTM, I studied for my PhD at the University of York. My thesis explored the accessibility and acceptability of HIV services in the UK to adults receiving a positive HIV diagnosis at age 50 years and over, using a mixed-methods approach. For this project, I performed qualitative interviews with adults diagnosed with HIV at age 50+ years and healthcare professionals (HCPs) working in sexual health/HIV services. I also conducted a survey of HCPs working in sexual health/HIV services and analysed national GUM attendance and HIV testing data by age.  

I completed my BSc in Evidence-Based Nursing Practice (Adult) at the University of York in March 2011. Following this, I worked as a staff nurse on a haematology and oncology unit and as an oncology research nurse before starting my PhD in September 2013.

I am a seminar leader on the Principles of Social Research module.


I work on projects to explore vaccination programme uptake and delivery in the UK. My research particularly focuses on underserved communities, including minority ethnic and migrant populations. My current projects focus on experiences of accessing routine childhood vaccines during the COVID-19 pandemic, COVID-19 vaccine views and behaviours, and COVID-19 vaccine programme delivery. This research is being conducted as part of the Health Protection Research Unit in Immunisation, a partnership between LSHTM and Public Health England.

I am also working on a qualitative project in Western Uganda to explore how social norms operate in relation to violence against children. This research is looking at how power dynamics and social norms have changed following the implementation of a school and community based program intended to prevent violence against children.
