Lina Zgaga was appointed as Associate Professor of Epidemiology in the Department of Public Health and Primary Care in 2013, having previously worked in the Centre for Population Health Sciences and Institute of Genetics and Molecular Medicine at the University of Edinburgh, UK.

Research Interests

Research interests include: (1) vitamin D deficiency, its prevalence and effects on human health, including investigation of the role of vitamin D deficiency in cancer occurrence and progression, obesity and chronic disease; (2) genetic epidemiology, including colorectal cancer genetics and identification of genetic loci that are associated with human traits; (3) epidemiology of glycans in health and disease, (4) gene-environment interaction studies and (5) the role of psychosocial environment on health.


Starting in the next academic year (2013/2014), she will be responsible for teaching epidemiology to medical undergraduates. Since 2005, she has been teaching epidemiology to 6th year medical students at the Medical School, University of Zagreb.

Service to College and Community

She has acted as referee for several journals, including PLoS Medicine. She is a founding member of the Journal of Global Health and currently serves on the editorial board. She has participated in several public engagement events and round tables with academics and policy makers.
