I am head of the Department of Global Health and Development, having previously been head of the Anthropology, Policy and Politics Group in that Department. My main research interests lie in analysing the health policy and systems development issues in relation to population, sexual and reproductive (including maternal) health and services - and how these relate to the SDGs and changing climate contexts for global development.  I have conducted research at policy, health systems, health service and community levels in a wide range of countries.

In sub-Saharan Africa a large body of my work has been exploring the integration of reproductive health and HIV/AIDS services to understand how policies are translated into practice and how policies and programme structures affect service delivery. I wasPI on the Integra Initiative, a Gates-funded five-year research programme (and its 18 month follow-on), to evaluate different models of delivering integrated RH/HIV services in Kenya and Swaziland.

I was also PI on an ESRC-DFID funded 3-year research project to examine the accountability of global, bi-lateral and national institutions involved in climate change policy and governance, with a focus on vulnerability, climate-change adaptation capacity and the impact of population dynamics.

Under previous DFID Research Programme Consortia (RPCs) I coordinated work under the theme of 'Integration' for the DFID RPC on 'Reproductive Health and HIV' and managed LSHTM's component of another DFID RPC on 'Reproductive Health and Rights'. At community and service delivery levels in Ghana, my early work identified community perceptions and use of STI/HIV services. I was a core partner on an EU-funded research project in Ghana on perceptions of Emergency Contraception among urban dwellers and providers, as part of a four-country study comparing acceptability and accessibility of EC in Ghana, Burkina Faso, Senegal and Morocco.

In Asia, my work has been concentrated in Pakistan where I led components of two projects investigating the health needs and service provision for marginalised groups at risk of HIV (sex workers and injecting drug users) and documenting their experiences of abuse.

My systems level work has included investigation of decentralisation dynamics in sub-Saharan Africa (with the Nuffield Institute for Health, Leeds) and an analysis of attempts to contract NGOs to deliver HIV services to marginal groups in Pakistan (with a doctoral student).

Also with doctoral students I am building up a series of case studies testing, critiquing and developing theoretical approaches and techniques for health policy development and implementation analyses.
