Bea is a professor of Economics and Food Policy at the Friedman School of Nutrition Science and Policy. She served as Academic Dean of the School for 13 years, and is currently Director of the school's Food Policy and Applied Nutrition Program. Bea's career combines teaching in a graduate program to prepare students for careers in food and nutrition policy in the US and globally, and conducting field research on food policy and programs, mostly in developing countries. Her research focuses on economic determinants of household food consumption, including price policy, food aid, food price subsidies and income transfers. Her current research is on a project for the US Agency for International Development assessing the programmatic uses and nutritional quality of food aid commodities. As part of this project, she is conducting studies in three sub-Saharan African countries to assess the use, effectiveness and cost-effectiveness of alternative nutritional supplements for the prevention and treatment of moderate acute malnutrition in children.  She recently completed a study that focuses on how the effects of food assistance programs can be made sustainable after the programs are closed (a four year project conducted in Bolivia, Honduras, India, and Kenya).  She has conducted research on the determinants of intra-household allocation of resources, focusing on the role of female household headship among other factors. Previous work included the application of  the statistical technique of Small Area Estimation to the assessment of the distribution of malnutrition prevalence at geographically disaggregated levels using census and survey data in combination. She also has conducted research on curricula to prepare global food policy professionals and on their career trajectories. Most of her research has been in less developed countries, including Malawi, Burkina Faso, Sierra Leone, Pakistan, India, Thailand, the Philippines, Cameroon, Dominican Republic, Jamaica, Republic of Mali, Morocco, Mozambique, Honduras, Bangladesh, Bolivia, Peru, and Brazil, but she has also conducted research in the US on food stamps and their relationship to household food security, and on construction of alternative poverty line for the US.
