Nuala McGrath is Professor of Epidemiology and Sexual Health, and works primarily on HIV and STIs in Sub-Saharan Africa. In the UK, she is evaluating strategies to improve effectiveness and efficiency of the sexual health service and develop interventions targeting sexual risk behaviours associated with substance misuse.

 

Nuala received her undergraduate degree in Mathematics, Statistics and Operational Research (University of Exeter, UK); a Masters in Biometry (University of Reading, UK); and a Doctorate in Infectious Disease Epidemiology (Harvard School of Public Health, USA). In the last 15 years, she has been the Principal Investigator of the Microbicides Development Programme feasibility study preparing for the phase III trial at the Africa Health Research Institute (formerly Africa Centre for Health and Population Studies) in rural KwaZulu-Natal, South Africa;  Field Director of the Wellcome Trust funded Karonga Prevention Study site (London School of Hygiene and Tropical Medicine) in rural Malawi; and as a Wellcome Trust Career Development Fellow led a programme of work focusing on sexual behaviour and partnership dynamics in the era of ART in KwaZulu-Natal.  She was also lead statistician on the first couples-based intervention randomised controlled trial to have couples HIV counseling and testing as its outcome, NIH-funded; Steering Committee member of both the NIMH-funded Project Accept and the ANRS Treatment as Prevention Trial; Independent Data and Safety Monitoring Board statistician for two international HIV clinical trials; Malawian National Ethics Committee member, and previously held an Honorary Professor appointment with the School of Nursing and Public Health, University of KwaZulu-Natal, South Africa.

She currently holds an honorary appointment with the Research Department of Epidemiology & Public Health, University College London (Reader). She serves as a member of the Wellcome Trust Basic Science Postdoctoral Fellowship Interview Committee, the Commonwealth Scholarship Commission in the UK, and the NIHR UK PANTHEON steering committee.

Research interests

Nuala’s current programme of international work is characterised by two main areas of research: a) HIV testing, prevention and treatment; b) Sexual and reproductive health and relationship dynamics.

 

a) HIV testing, prevention and treatment

The research questions and setting of her HIV-related research has changed over her career mirroring the progress and responses to the HIV epidemic globally. From 1989, Nuala was involved in the first US trials to identify appropriate treatment for HIV-infected children. She shifted focus to epidemiological and intervention studies in SSA as the severity of the epidemic there became apparent, and multi-countries studies between Africa and Asia. Her research has spanned the period before international roll-out of HIV treatment and the current era of the challenges of lifetime treatment and multimorbidity.  

Currently, she is co-investigator of a factorial design RCT in KwaZulu-Natal, funded by NIH (2016-2021), to test the effect of financial incentives and an electronic patient-centred decision support tool on uptake of HIV testing and linkage to care. 
 
b) Sexual and reproductive health and relationship dynamics

Nuala is also interested in changes in sexual behaviour and sexual health practices e.g. vaginal washing, in relation to ART availability and whether such behaviours facilitate HIV and STI transmission and acquisition.

Currently, she is co-investigator of an impact evaluation of PEPFAR’s DREAMS (Determined, Resilient, Empowered, AIDs free, Mentored and Safe) Initiative to reduce HIV incidence among adolescent girls and young women in South Africa (funded by the Gates Foundation). In addition, she is co-investigator of an NIH-funded grant (2017-2022) that aims to maximise uptake of combination HIV-prevention strategies by adolescent girls and young women (AGYW) and retention of AGYW in HIV prevention programmes. She also leads analyses of population-based data to describe trends in sexual HIV risk behaviours and knowledge of HIV in rural youth.  

Involvement in STI and HIV-related research in the UK

Nuala is a steering committee member for the ‘Prevention and Testing for HIV: Economics and Outcomes of Novel Approaches’ (PANTHEON) programme evaluating cost-effectiveness of HIV self-testing among MSM in the UK. Through the NIHR Collaboration for Leadership in Applied Health Research and Care (CLAHRC) Wessex, she collaborates with the Solent NHS Trust Sexual Health Services team on intervention development around substance misuse and high STI risk sexual behaviours. She is also a member of the University of Southampton’s Centre for Sexual Health Research.

Couples as a cross-cutting theme

Couples-focused health research cross-cuts all areas of Nuala’s research and is an expanding, innovative and distinctive feature of her research career. Given that partners have a significant influence on each other’s health and are similar in health status and health behaviours, couple-focused interventions for health behaviour change may be more effective than individual interventions.

Nuala undertook a systematic review of interventions of health behaviour change for couples with at least one member at risk of a chronic illness and in South Africa she has investigated the health benefits of partnership for men, methods of recruiting non-cohabiting couples, the role of social support in loss-to-follow-up in ART programmes, gender equality within partnerships and condom use and, relationship quality and alcohol use. She collaborates with colleagues in Malawi and Nigeria on projects using couple-based approaches in Option B+ and family planning. She supervises University of Southampton MSc and PGR students conducting couples-focused analyses of quantitative and qualitative data including dyadic analyses.
