Miss Nerissa Tilouche

Research Fellow

United Kingdom

I am a mixed methods social scientist interested in evaluations of public health interventions.

 

I currently work across three research projects:

 

The Learning Initiative on Norms, Exploitation, and Abuse (LINEA) is a preventative intervention comprising two curricula and a radio drama, designed to shift the social norms and behaviours that drive age-disparate transactional sex (ADTS) among 13 to 15-year-old girls and men in Mwanza, Tanzania. We are conducting a cluster randomised controlled trial to assess the impact of the LINEA radio drama alone versus the radio drama combined with the curricula.

 

The Serious Youth Violence Project uses a participatory photography research approach (photovoice) to understand perceptions of safety in public spaces among young people aged 12–16 who are at risk of serious youth violence — violence between young people, such as knife crime and other weapon-enabled offences, that causes serious physical or emotional harm. We are working with local community organisations in London and Bristol to recruit and train young people as 'peer researchers', who will help us design the research activities and run the workshops.

 

The Improving Hospital Opioid Substitution Therapy (iHOST) study is a mixed-methods evaluation of an intervention to improve opioid substitution therapy in three acute hospitals in England. The project was extended to finalise a best practice guideline to be shared nationally, and I am currently working with colleagues on papers and dissemination.

 

I joined LSHTM in 2016 as a Project Coordinator and was awarded a two-year NIHR Pre-Fellowship in 2019 to develop my mixed methods research skills, as part of which I completed the MSc in Public Health at LSHTM in 2020. I then worked as a Research Assistant on the Positive Choices Trial before moving into my current roles.
