He has co-authored over 100 peer-reviewed scientific publications and an introductory infectious disease modelling book. He is currently PI/LSHTM PI of six research grants: this TB Modelling and Analysis ConsortiumDetermining the importance of different locations to Mycobacterium tuberculosis transmission in high tuberculosis burden settings (MRC), A Clinical Trial of a Correlate of Risk Targeted Screen & Treat Strategy to Impact TB Control (BMGF), The development of a mathematical modelling framework to predict the best dose in humans for TB vaccines using animal data (Aeras), 'Methods for allocative efficiency of the Global Fund TB, HIV and Malaria Country Grants' (USAID), and 'Data utilization and modelling to support TB control policy and practice in South Africa' (BMGF).

Ted Cohen

Ted 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. Dr. Cohen's training is in epidemiology and clinical medicine, and his work includes mathematical modeling, fieldwork, and analysis of programmatic data. His research program is currently funded by NIH, US CDC, and Gates Foundation Awards.


David Dowdy


David Dowdy is an epidemiologist and practicing general internist whose research merges expertise in classical epidemiology, economic evaluation, infectious disease modeling, and translation of science into policy.  David received his MD and PhD (in epidemiology) at Johns Hopkins in 2008 and completed his residency training in internal medicine at UCSF in 2011.  His primary body of work involves modeling the population-level impact and cost-effectiveness of diagnostic interventions for tuberculosis (TB).  Other efforts and areas of interest include heterogeneity in TB transmission, active TB case-finding, development of "user-friendly" modeling tools for TB, costing of HIV prevention interventions, and evaluation of TB therapeutics and vaccines. 

Philip Eckhoff


Philip Eckhoff is currently the Principal Investigator of the disease modeling team at Intellectual Ventures in Bellevue Washington. This group develops computer simulations of malaria, polio, and other disease transmission dynamics to assist public health professionals and other scientists in planning eradication of different diseases. These simulations have resolution of individuals but cover large geographic areas and are focused on studying all phases of a Global Eradication campaign. Beyond modeling disease Eradication, his research interests include technologies for improved public health in the developing world and other global development issues, such as vaccine delivery and sanitation.

Philip completed his undergraduate studies at University of Texas, Austin receiving degrees in pure mathematics and aerospace engineering. At UT, he participated on the winning design team for FASTRAC, a student designed and built satellite for the Nanosat-3 competition. Philip began his graduate studies at Princeton University in applied and computational mathematics, receiving his PhD in 2009. At Princeton, his work focused on computational neuroscience and biophysics-motivated models of decision making. While at Princeton, he began work on malaria and mathematical models of disease transmission, having had malaria frequently while growing up in Haiti.

Philip received a Special Achievement Award by a Hertz Fellow in 2009 for his work on Malaria Modeling. He enjoys hiking and kayaking in the Pacific Northwest and attending Seattle Symphony performances.

Nick Menzies


Nick Menzies is Assistant Professor of Global Health in the Department of Global Health and Population at the Harvard Chan School of Public Health, and faculty of the Harvard Center for Health Decision Science. Professor Menzies 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.

Anna Vassall


Anna Vassall is a health economist with around twenty years experience economic analysis. She first worked in the NHS supporting funding/contracting. She then took an MSc in Health Planning and Financing at the LSHTM, thereafter working for DFID as a health economist in the UK and Pakistan. This was followed by a period at Royal Tropical Institute (KIT) Amsterdam working on health planning and financing, aid effectiveness and the cost-effectiveness of tuberculosis and reproductive health in a wide range of low and middle income countries. For the last few years, she has been managing European Community and World Bank funded health sector reform and development projects in Yemen, East Timor, Syria and Sudan. Her PhD is in the economic evaluation of tuberculosis control.

Anna's research interests are in the economic evaluation of HIV (with a focus on efficiency, integration, scaling-up and systems costs estimation) and aid effectiveness. She is a member of the Social and Mathematical Epidemiology Group, within Global Health and Development.

David Wilson


David Wilson, PhD in infectious disease modeling, is a Senior Program Officer in Decision Sciences at the Bill & Melinda Gates Foundation. Prior to joining the Foundation, David was a Professor of Modeling & Health Economics at the Burnet Institute and Monash University in Australia, and CEO of the Optima Consortium for Decision Science, where he was leading teams conducting applied research into improving efficiency in health responses. In 17 years as an academic prior to joining the Gates Foundation, his dominant focus was on allocative efficiency for major infectious diseases (with special focus on HIV) although has also worked in other areas of health and complementary methods. This includes, for six years being the Head of Public Health Surveillance in Australia for blood-borne viruses and STIs. Most of his work has been conducted to support LMIC governments and their local or global partners to make better decisions for health through the generation, synthesis and promotion of quantitative evidence including surveillance, modeling, health economics and resource allocation, strategic target setting, supporting strategic purchasing and financing, and capacity building in countries for the translation of evidence to policy and programming. Working in approximately 40 countries on all continents, he has published over 230 scientific papers and delivered over 500 scientific addresses.

The development and analysis of mathematical models of the transmission dynamics of STDs provides a framework to analyse surveillance and survey data and observational cohort studies. Prof. Garnett’s main aims have been to develop and understanding of the patterns of sexual behaviour involved in STI spread and to understand the potential impact of behavioural and health care interventions.

With a background in population ecology, Prof. Garnett’s PhD was on the epidemiology of varicella-zoster virus; exploring the relationship between chickenpox and shingles and the impact of the varicella vaccine. Before taking up a faculty post at Imperial College London, Prof. Garnett held a Wellcome Trust Training Fellowship in Mathematical Biology and a Royal Society University Research Fellowship

Since 1990 Prof. Garnett has worked on the broad area of HIV and STD epidemiology, with projects on the demographic impact of AIDS; modelling sexual partner networks; the epidemiology of HIV, gonorrhoea, syphilis, trichomoniasis, herpes-simplex virus and human papilloma virus. Recent work has focussed on the potential impact of HPV vaccines the epidemiological consequences of antiretroviral treatments and the evaluation of HIV Prevention programmes.

Prof. Garnett has been an investigator on community randomised trials of HIV interventions in Zimbabwe and Peru and has been involved in the design and analysis of a number of sexual behaviour surveys in developed and developing countries. As Chair of the UNAIDS Reference Group on Estimates, Models and Projections Prof. Garnett has played a part in developing the methods used in HIV surveillance globally.
