My research integrates diet, lifestyle and other modifiable factors, biomarkers, and omics data with the aim at advancing the understanding of the etiology of cardiovascular diseases, cancer, and other chronic diseases. In addition to traditional epidemiological study designs, I have extensive experience of the Mendelian randomization design, which uses genetic variants as instrumental variables for the modifiable factor to reduce bias and confounding in observational data. The overall aim of my research is to improve the knowledge on disease prevention.
