Dr Charlotte Watts
A mathematician and epidemiologist with further public health training. I have over ten years experience working on HIV/AIDS. My main research interests include using epidemiological modelling and economic analysis to inform HIV/AIDS policy, the development of new methodologies to inform intervention planning, evaluation and resource allocation; interventions to address women's vulnerability to HIV infection; and the links between violence against women and HIV/AIDS. Since 1997 I have been involved with numerous research collaborations in Southern and West Africa, Bangladesh, Thailand and the Ukraine. Previously I have worked with the Global Programme on AIDS, and with non-governmental organisations in Zimbabwe. Currently I am a member of the technical advisory group to the Impact Project, Family Health International, and for the Frontiers Prevention Program of the International HIV/AIDS Alliance, and am Senior Technical Advisor to the WHO multi-country study on women's health and domestic violence.

Dr Lilani Kumaranayake
An economist specialising in HIV/AIDS and econometric modelling for health policy analysis. I have worked in a range of countries in Sub-Saharan Africa, Eastern Europe, and Asia. I am currently undertaking research related to economic evaluation, development of new methodologies for assessing costs and resource allocation, and HIV/AIDS and health systems. I have been a technical advisor to international organisations such as the WHO, UNFPA, UNAIDS and the World Bank and currently belong to the WHO TB/HIV Working Group and the UNAIDS Reference Group on Economics.

Dr Peter Vickerman
A mathematician with a DPhil in mathematical biology from the University of Oxford. My focus is on using epidemiological modelling to understand the determinants of HIV transmission and intervention impact of different HIV prevention strategies, and to obtain effectiveness estimates for use in cost-effectiveness analysis. Since joining the HIVTools Research Group I have developed ten deterministic dynamic epidemiological models of intervention impact, and have been involved with research collaborations in Bangladesh, Belarus, Ukraine, and South Africa. I have a particular interest in using models to understand the determinants of HIV transmission and intervention impact among injecting drug users, and have presented findings of this analysis at several international conferences.

Fern Terris-Prestholt
An economist with experience in the economics of HIV prevention. I have undertaken cost analyses of a variety of HIV prevention and care projects in Uganda, Tanzania, Zambia and South Africa. Projects include STD treatment, condom promotion, VCT and projects targeted to youth and sex-workers. I am currently focusing on the economics of microbicides and barrier methods, particularly relating to potential demand and costs.

Lorna Guinness
An economist specialising in the economics of HIV/AIDS in low-income countries. I am a Wellcome Trust research fellow exploring the economics of scaling up HIV prevention programmes in South India using a new institutional economics framework. I also have experience in the economic evaluation of HIV/AIDS interventions in Bangladesh, India, Kenya and Ukraine. I have published literature reviews on the economic impact of AIDS and the cost-effectiveness of HIV/AIDS interventions in sub-Saharan Africa. Prior to joining LSHTM, I worked as an economist at UNAIDS in Geneva and consultant health economist in South Asia and sub-Saharan Africa, for the Asian Development Bank, DFID and UNICEF.

Anna Foss
A mathematician with a MMATH in mathematics. Since joining the HIVTools Research Group I have been working on exploring the potential impact of shifts in condom use following microbicide introduction and modelling the impact of HIV prevention interventions in Bangladesh. My research interests include using mathematical modelling to explore the potential role of different new technologies in HIV prevention.
