    Timothy Hallett

    Director

    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

    Senior Lecturer

    Jeff is a Senior Lecturer within the Department of Infectious Disease Epidemiology, working 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.

    Isaac Stopart

    Research Assistant

    Isaac joined the HIVMC in 2017. His research interests include the impacts of social and environmental drivers on infectious disease transmission, and the optimal allocation of resources to minimise the number of new infections. Under the supervision of Dr Jessica McGillen and Prof Timothy Hallett, he is currently using mathematical modelling techniques to optimise the allocation of resources for HIV/AIDS. He is specifically concerned with the impact of real-world supply and demand side constraints, such as procurement cycles and stigma, on the optimal allocation of interventions. Isaac obtained his BSc at Imperial College London, focusing on epidemiology and ecology,  after which he worked for a specialist fisheries consultancy.

    Sumali Bajaj

    Research Assistant

    Sumali joined the HIV Modelling Consortium in November 2017 after completing my Masters in Biostatistics from Harvard T.H. Chan School of Public Health. Previously, she has worked as a research assistant at the Department of Social and Behavioural Sciences, HSPH on a project funded by UNICEF looking at the determinants of child stunting in India and as a research assistant with the Research Program on Children and Global Adversity group on their "Former Child Soldiers of Sierra Leone: A Longitudinal study of War" project at HSPH.  She holds a Bachelors in Statistics from Lady Shri Ram College for Women, University of Delhi, India and have worked with All India Institute of Medical Sciences and Public Health Foundation of India. Currently, she is working on developing a hierarchical bayesian spatial model for small area estimation of some HIV indicators.

    Oliver Geffen Obregon

    Research Assistant

    Oliver works at the HIV Modelling Consortium on the evaluation of HIV epidemic models projections under the supervision of Dr Jeff Eaton and Prof Tim Hallett. He holds a MRes in Systems and Synthetic Biology from Imperial College London, where he worked on the acquisition of drug resistance in staphylococcus aureus, and an MSc in Public Health (Health Economics) from the London School of Hygiene and Tropical Medicine. At the London School, he analysed Unitaid survey data, estimating regional level out-of-pocket expenses and time invested in health facility visits for people living with HIV (PLHIV). As a result of this , he has participates in a UNAIDS scoping review of the impact of user fees on access to health services among PLHIV in West Africa. Prior to coming to Imperial, he taught Molecular Biology at the University of Tel Aviv and worked as an STI counselor at the Israeli Ministry of Health.

    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.
