I am both an agricultural and health economist, with over 25 years of experience working in low and middle income countries in Asia, Africa and Latin America. I am an expert in two domains for global health and development. The first is in the area of health economics, where I conduct economic evaluations of new and modified technologies, programs and policies for advancing public health in developing countries. The second is in the area of food security and nutrition policy, where more recently I've focused on implementing and evaluating integrated agriculture and health projects to maximize health and nutrition outcomes.
Currently, I am a clinical associate professor at the University of Washington's Department of Global Health. My research focuses estimating costs and cost-effectiveness of health technologies and interventions in public health delivery systems, including interventions that work across sectors to maximize health and nutrition. Previously, I provided technical guidance and coordinated the economic analysis for the Disease Control Priorities Third Edition—a nine-volume series aimed at strengthening evidence based priority setting in health and nutrition. From 2016 to 2019, I was the director of the Global Health Cost Consortium to generate improved estimates of costs for HIV and TB for use in planning, budgeting and economic evaluation. I am now the director of the project ‘Strengthening the Economic Evaluation of Multisectoral Strategies for Nutrition (SEEMS-Nutrition)’. Previously, I was a Senior Health Economist at PATH, an international non-profit in Global Health from 2000 to 2012. Before that I was a Research Fellow at the International Food Policy Research Institute from 1994 to 2000.
