Eaton co-chairs the UNAIDS Reference Group on Estimates, Modelling and Projections, a technical advisory group that provides scientific guidance to UNAIDS and partner organizations on the data, methods, and tools used to quantify the global HIV epidemic. His team in the MRC Centre for Global Infectious Disease Analysis at Imperial College London develops software tools used annually by national HIV programmes to produce national and subnational epidemiologic estimates to guide their response to HIV, in collaboration with UNAIDS, PEPFAR, Global Fund, CDC, and other organizations. He has a longstanding interest in demographic surveillance, population cohort studies, and methods for collecting and analysing longitudinal data. Key collaborations include with the Manicaland Centre for Public Health Research in eastern Zimbabwe and the ALPHA Network of population HIV cohort studies.

Dr. Bill Hanage is a Professor of Epidemiology at Harvard T. H. Chan School of Public Health. His research and teaching focus on the epidemiology of infectious disease and the evolution of infectious agents. He received his PhD from Imperial College London. Dr. Hanage has made seminal contributions to the study of diverse pathogens, both bacteria and viruses, and has a special interest in evolution in response to interventions such as vaccination or antimicrobials. His research on the current pandemic has included modeling transmission in healthcare and the impact of vaccination in the context of variants, how fatality rates vary with age, and how the virus evolves in individual hosts. His awards include the Fleming Prize from the Microbiology Society and a young investigator award from the American Society for Microbiology. He has published more than 200 scientific articles and book chapters and is a regular contributor to popular media aiming to improve public understanding of the SARS-CoV-2 pandemic and other infectious diseases.

Nick Menzies is Associate Professor of Global Health in the Department of Global Health and Population, and part of the core faculty of the Harvard Center for Health Decision Science. Professor Menzies uses decision science and quantitative research to understand the consequences of policies to combat major infectious diseases, and help design effective disease control programs when resources are limited.
Professor Menzies combines empirical data with mathematical modeling to examine infectious disease control policy in high burden settings, currently focusing on the intersection of HIV and TB epidemics in sub-Saharan Africa and other high-burden settings.
In his empirical research Nick has worked to improved the level of evidence on the resource requirements for HIV interventions in high burden settings, allowing for better budgeting of these large programs and allowing decision-makers to weigh the advantages of different implementation approaches. Nick is currently working on a multi-country study to understand the costs, cost drivers and efficiency determinants of routine immunization services. Other applied work has addressed the costs and benefits of expanding access to HIV screening and diagnosis in high prevalence settings. Read more.

Dr. Ruanne Barnabas is a physician-scientist, Chief of the Division of Infectious Diseases at MGH, and a Professor of Medicine at HMS.
Over the last 15 years, her research has focused on interventions for HIV and STI treatment and prevention. She is particularly interested in novel approaches that increase access to services. She is the Principal Investigator of the KEN SHE Study that demonstrated high efficacy of single-dose human papillomavirus (HPV) vaccination in Kenya and contributed evidence to the World Health Organization (WHO) policy supporting single-dose vaccination globally. She has led clinical trials with companion health economic modeling to assess interventions’ potential health and economic impact. Her work aims to identify effective and scalable HIV, HPV, and infectious disease treatment and prevention strategies to increase access across diverse communities and promote equity in health.

Dr. Caroline Buckee is a Professor of Epidemiology at Harvard T.H. Chan School of Public Health. Her work is focused on understanding the mechanisms driving the spread of infectious diseases that impact the most vulnerable populations worldwide, particularly malaria. Before coming to Harvard, Dr. Buckee completed a D.Phil. at the University of Oxford, and Omidyar and Wellcome Trust fellowships at the Santa Fe Institute and the Kenya Medical Research Institute, respectively, where she analyzed malaria parasite evolution and epidemiology. Dr. Buckee’s group uses a range of mathematical models, experimental and genomic data, and “Big Data” from mobile phones and satellites to understand how human pathogens spread and may be controlled. Her work has appeared in high profile scientific journals such as Science and PNAS, as well as being featured in the popular press, including CNN, The New Scientist, Voice of America, NPR, and ABC.
