Professor Emeritus
Division of Nutritional Sciences


My interests relate to the formulation, implementation and evaluation of nutrition policy, primarily in low and middle income countries.  I approach this work from a transdisciplinary, engaged and problem-oriented perspective, in which the key research questions and choice of methods emerges in the course of engaging with policy and program actors at global, national or sub-national levels.  This approach is guided by robust theoretical frameworks and ensures that the research is responsive to real-world concerns and more likely to be understood, valued and used by those responsible for policies and programs.

Recent research activities: Improved methods for nutrition policy analysis and development; mainstreaming nutrition in Peru, Bolivia, Guatemala, Vietnam and Bangladesh; policy commitment for addressing the dual-burden of malnutrition in Nigeria; development and testing of a micronutrient program assessment tool; evaluation and strengthening of the World Vision mobile clinic program in Haiti; exploring the potential for knowledge brokers to enhance policy implementation in complex adaptive stakeholder systems in Burkina Faso, Mali, Ethiopia and Uganda; a project to strengthen the theory and practice of nutrition policy advocacy in seven SE Asian countries as well as Ethiopia and Burkina Faso; and an implementation science initiative in Kenya and Uganda to strengthen the implementation of large-scale anemia control programs and document the practice of implementation science in real-life settings.

My public engagement goals have been to develop, promote and apply improved methods for policy analysis, development and implementation, primarily in low and middle income countries.  I maintained an active portfolio of public engagement activities for this purpose, including interactions with institutions such as the Scaling Up Nutrition Secretariat (Geneva, Switzerland), the nutrition units in international organizations such as The World Bank, WHO, UNICEF, USAID, the Global Alliance for Improved Nutrition, the UN Standing Committee on Nutrition, The International Food Policy Research Institute, the National Information Platforms for Nutrition and the governments of countries where i have research collaborations. In addition, I pursued these goals through my role as current Past-President of the Society for Implementation Science in Nutrition.


There is a saying that "the world has problems and universities have departments." (aka disciplines).  When it comes to food, nutrition and health problems we must go beyond disciplinary knowledge, indeed beyond the walls of the university, to find possible solutions.  This perspective underlies my approach to knowledge, teaching and advising: problem-oriented, transdisciplinary and contextual.   This not only prepares students to be more effective professionals and problem-oriented researchers, it also is a more interesting and engaging way to teach and learn.
