    Timothy Hallett


    Timothy Hallett is a Professor of Global Health based at the Department of Infectious Disease Epidemiology.  His work centres on the development and application of mathematical models for interpreting surveillance data, analyzing trials and planning interventions.  The overall aim of this research is to come to conclusions about the optimal use of limited resources in response to the HIV epidemic worldwide.  He is the Director of the HIV Modelling Consortium.


    Jeffrey Eaton

    Research Fellow

    Jeff is a researcher with the HIV Modelling Consortium. His main research interests include understanding the epidemiological impacts of antiretroviral therapy on HIV epidemics in sub-Saharan Africa, improving methods and surveillance data for estimates of HIV trends, developing and validating mathematical models used to inform HIV policy decisions in generalized epidemic settings, HIV in children and adolescents in southern Africa, and data collection, analysis, and modelling of general-population HIV cohort studies. He holds a PhD in Infectious Disease Epidemiology from Imperial College London, and Master's degree in Statistics from the University of Washington. He was worked at demographic surveillance sites: the Agincourt Health and Population Unit in rural northeastern South Africa and the Mekong Integrated Population Registration Areas of Cambodia (MIPRAoC). He collaborates extensively with the Manicaland HIV/STD Projection, a population-based HIV cohort in eastern Zimbabwe, and contributes to the UNAIDS Reference Group on Estimates, Modelling, and Projections and the Economics and Modelling working group of the HPTN 071 (PopART) community randomised trial of a combined HIV prevention package including test-and-treat.


    Jessica McGillen

    Research Associate

    My current research interests lie in how geospatial heterogeneities in human behaviour and movement impact the HIV/AIDS epidemic, and how treatment and prevention efforts can be optimised by accounting for these heterogeneities to more effectively alleviate the HIV disease burden across Sub-Saharan Africa.

    During my PhD in the Wolfson Centre for Mathematical Biology at Oxford University, I used continuum mathematical models to study the role of altered cellular metabolism in the spatial patterning and invasive dynamics of growing cancer tumours. Prior to this, I completed an MSc in Computational Biology at Carnegie Mellon University in Pittsburgh, USA, where I developed simple models of within-host HIV infection dynamics.


    Jack Olney

    Research Assistant

    Jack joined the HIV Modelling Consortium in 2012 after completing his Master's in Infectious Disease Epidemiology at Imperial College London. He is currently pursuing a PhD investigating how strengthening HIV treatment programmes in sub-Saharan Africa can improve patient outcomes, while assessing the role patient health care seeking behaviour has on HIV care


    Ellen McRobie

    Research Assistant

    Ellen began working for the Modelling Consortium in October 2012 as the Project Manager. Ellen holds a Master's degree in Reproductive and Sexual Health Research from London School of Hygiene and Tropical Medicine and a Bachelor's degree in Physiology from the University of Bristol. In May 2016 Ellen began working as a Research Assistant for the HIV Modelling Consortium looking at the influence of targets set by global organisations on country-level decision-making processes.

    Prior to working in the Consortium she worked for the Small Area Health Statistics Unit and MRC-HPA Centre for Environment and Health where she managed the production of the Environment and Health Atlas for England and Wales. She also has several years experience working as an account manager and medical writer focusing predominantly on events and materials relating to clinical management of chronic hepatitis B. In this role she assisted in the running and content development of a number of large physician education events in Europe, USA, and Asia. 


    Sarah-Jane Anderson

    Research Assistant

    Sarah-Jane recently completed her PhD at Imperial College London, focusing on how to design HIV combination prevention programmes to maximise impact. Her current research interests lie in using mathematical modelling to understand the role of different prevention interventions in optimised prevention strategies, with a particular focus on how they can be strategically prioritised to reflect the differences in risk of transmission across populations and geographies.


    Soraya Rusmaully

    Project Manager of the HIV Modelling Consortium

    Soraya joined the HIV Modelling Consortium in July 2015 as the Project Administrator following completion of a Master’s degree in Health, Community and Development at the London School of Economics and Political Science. In June 2016, she became the Project Manager of the Consortium.

    Sabrina Lamour

    Project Manager of the HIV Modelling Consortium Models for Program Planning Reference Group

    Sabrina Lamour joined the HIV Modelling Consortium as a project manager for the Models for Program Planning Reference Group in July 2016, after obtaining her PhD in Clinical Medicine Research and a MRes in Biomedical Research, both at Imperial College London. She had obtained her degree in Biomedical Sciences from Durham University. Her research background had been focused on investigating host responses in tropical infectious diseases, particularly parasitic and viral infections, and has also included voluntary clinical work in southern Cote d’Ivoire. Prior to this, Sabrina was employed as a Research Associate for UCB Pharma  in immunology.
