My main interest is sustainable lifestyle and health. I have a background in nutrition with focus on dietary factors, physical activity and weight management and risk of cancer. This research is combined with research on climate change to study diet-related greenhouse gas emission. Moreover, I have developed and validated a large number of interactive-web questionnaires on diet and physical activity for epidemiological research studies. I have worked at Harvard School of Public Health and Stanford School of Medicine as well as the Karolinska Institutet.
