Anna Bershteyn

Anna is a Senior Research Manager of the HIV/TB center at the Institute for Disease Modeling, and an Affiliate Assistant Professor of Global Health at the University of Washington. Her modelling research focuses on HIV transmission dynamics and impact evaluation of biomedical and programmatic improvements to HIV care and prevention.

Geoff Garnett

Geoff is a Deputy Director of Global Development and Global Health at the Bill and Melinda Gates Foundation. He works on improving the efficiency and effectiveness of health programs, with a particular focus on HIV. Prior to the foundation, he was a professor in the Department of Infectious Disease Epidemiology at Imperial College London and a Reader at Oxford University working on the epidemiology, evolution and control of sexually transmitted infections. He has served as chair of the UNAIDS Reference Group on Estimates Models and Projections and on a number of Institute of Medicine and Wellcome Trust panels.

Nick Menzies

Nick is an Assistant Professor of Global Health at the Harvard Chan School of Public Health, and faculty of the Harvard Center for Health Decision Science. He uses decision science and quantitative research to understand the consequences of major policy change, and help design effective disease control programs where resources are limited. His research 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.

Previous Members

Jason Madan

Jason is a Professor in Health Economics at Warwick Medical School, and Director of Graduate Research Studies for the School. His research involves the application of economic methods to health technology assessment in a wide range of clinical settings, including tuberculosis. He is particularly interested in the use of decision modelling and Bayesian methods to inform health policy.

Chris Dye

Chris is a Director of Strategy in the Office of the Director General at the World Health Organisation, and a Visiting Professor of Zoology at the University of Oxford. His research has focused on the large-scale dynamics of tuberculosis, HIV/AIDS, malaria, Ebola and other infectious diseases. Amongst other topics, he has investigated the rise of tuberculosis linked to HIV/AIDS in Sub-Saharan Africa, and the spread and containment of antimicrobial resistance.

Anna Vassall

Anna is a Professor of Health Economics at the London School of Hygiene and Tropical Medicine. She leads the economic evaluation and priority setting group in the Department of Global Health at LSHTM and as part of the Centre for Health Economics in London (CHIL). She specialises in the economics of HIV, sexual and reproductive health, gender based violence prevention and tuberculosis (TB).

Ted Cohen

Ted is an Associate Professor at the Yale School of Public Health. He is an infectious disease epidemiologist with a primary research focus on tuberculosis. He is particularly interested in understanding how TB drug-resistance and medical comorbidities such as HIV frustrate current efforts to control epidemics, with an ultimate goal of developing more effective approaches to limit the morbidity caused by this pathogen.

James Trauer

James is a Senior Lecturer at Monash University, where he is Head of the Epidemiological Modelling Unit at the School of Public Health and Preventive Medicine. He undertakes research to improve the effectiveness of infectious disease control programs through modelling, with a particular focus on tuberculosis (TB) and emerging infections.
