My main research interest is understanding the importance of healthy lifestyles for the prevention of non-communicable diseases (NCDs) and promotion of population health. I am particularly interested in epidemiological studies on the association of physical activity, nutrition and obesity with cancer risk. My current research projects involve (i) use of repeated measures in longitudinal studies to assess the association between physical activity and NCDs, particularly cancer; (ii) burden of cancer attributable to lifestyle risk factors in Brazil; (iii) evidence synthesis and risk of bias in epidemiological studies; (iv) distribution of protective and risk factors for NCDs in the population
