I am a researcher in the area of public health nutrition with an emphasis on nutrition epidemiology. I hold a PhD from the University of Pittsburgh, USA. Since 2000 I am a faculty member at the Department of Public Health and leading the S. Daniel Abraham International Center for health and Nutrition. My research focuses on the association between diet and health in different age groups. As part of this wide topic, I am working on the development of dietary assessment methods for various age groups, using traditional and non-traditional methods. The non-traditional methods include the assessment of different exposures via food. These include dietary patterns, exposure to processed foods, exposure to pesticides, environmental load and food additives. In my studies I am investigating the relationships between these various nutritional exposures and outcomes such as  geriatric functional indices, obesity, diabetes, nutritional status etc. 

In recent years my research covers human studies on diet and health. These include pesticides exposure and cognitive function in the old age, Mediterranean diet and physical performance and falls, exposure to processed food and birth outcomes, vegetarian and vegan diet and birth outcomes etc. In recent years I started working on the joint relationship between healthy and sustainable food in relation to health outcomes. This are of research is becoming increasingly important as we recognize the interconnections between our food choices, the environment and human health. We created a food library that covers environmental foot print based on data that was provided by Prof. Kissinger. Based on this work we calculated the environmental impact of the Israeli diet, and now working on strategies for promoting healthy and sustainable diet.
