Her research focusses on the role of nutrition and underlying molecular processes in the aetiology of chronic diseases. She has built a track record on B-vitamins, related molecular one-carbon and kynurenine pathways, and chronic diseases including cardio-metabolic diseases, mental health, quality of life, and gastro-intestinal cancer (survivors). She integrates this expertise with her personal interest to study quality and timing of food intake. Anticipating to the emerging field of chrono-nutrition (food timing), which potentially has fundamental impacts on metabolism and chronic disease, she developed a questionnaire on dietary timing for observational studies.
