Yi-Qian Sun

Yi-Qian Sun is a Senior Researcher in the Department of Clinical and Molecular Medicine at the Faculty of Medicine and Health Sciences, Norwegian University of Science and Technology (NTNU). Her work focuses on epidemiology, causal inference, and the interplay between lifestyle factors (e.g., vitamin D, body mass index) and chronic diseases such as cancer, dementia, and oral health conditions.

• PhD in Medicine, Linköping University, Sweden (2004)
• Medical Degree, Capital Medical University, China (1992)

Her research combines genetic epidemiology, epigenetics, and biostatistical modeling to investigate causal relationships between risk factors and disease outcomes. She has led projects on vitamin D as a biomarker for lung cancer, causal links between oral health and systemic health, and Mendelian randomization studies for lifestyle-disease associations.

Recent publications highlight her focus on vitamin D metabolism, obesity-related disease risks, and oral-systemic health connections. Her work spans population-based (HUNT Study) and clinical research, utilizing databases like UK Biobank for cross-cohort analyses.

Prof. Sun collaborates internationally and applies advanced statistical tools (Stata, R) for study design and data analysis. She leads the HUNT4 Oral Health Study within the GLIDE2 Oral Health Genomics Consortium.
