Professor Sahn's research is focused on issues of poverty, inequality, and the economics of health, nutrition, and education. His main academic interest is in identifying the solutions to poverty, malnutrition, disease and low cognitive ability in developing countries. Presently he is engaged in a major study that looks at the determinants and impacts of key demographic and economic transitions of young women in Madagascar and Senegal with a focus on understanding the importance of family background, community environment, and public policy (including school access and availability of social services) in determining early life course transitions such as leaving school, entering the labor market, childbearing, and the health and nutrition of infants and young children. In addition to teaching and mentoring of graduate students, he devotes considerable efforts to training and capacity-building of research institutions in Africa and working with government officials and international organizations to integrate research findings into policy.

Paul Soloway, Ph.D.; Professor. Professor Soloway's research activities are in the area of epigenetics and includes several separate sets of projects.  One of these seeks to characterize the mechanisms regulating the epigenetic phenomena of DNA and histone methylation in mice using the Rasgrf1 gene as a model.  These methylation events are potent regulators of gene expression and respond to environmental variables, including nutrition, in ways that are stable and inheritable.  A second set of projects in collaboration with Prof. Barbara Strupp to characterize epigenomic mechanisms by which maternal choline supplementation leads to improved cognitive outcomes in the progeny.  Recent advances in epigenomic methods make this project tractable.  

Barbara Strupp, Ph.D.; Professor Emeritus, Director of Graduate Studies in the Division of Nutritional Sciences. Professor Strupp's research activities include maternal choline supplementation research using animal models, maternal choline supplementation research with human subjects; investigating whether the lasting cognitive benefits of maternal choline supplementation in the Ts65Dn mouse model of Down syndrome and normal littermates are mediated by epigenetics effects due to choline's role as a methyl donor and; collaborating on a project with collaborators at UC Santa Cruz and the University of Illinois to investigate the lasting cognitive and neural effects of early developmental exposure to Manganese.
