Researcher

PhD in Medicine 2026.
PhD project
Annie worked as a Ph.D. Student at the Department of Pediatrics in Karl Mårilds research group Gastrointestinal Epidemiology 2022-2026. In her PhD studies, Annie investigated early-life environmental factors and the risk of inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. Environmental factors included diet, hygiene factors, as well as exposure to infections and antibiotics. Large-scale data from the Swedish ABIS and Norwegian MoBa cohorts were used, and the project included over 100,000 children followed from birth to later adolescence/early adulthood. Annie's doctoral project was part of a collaboration between the University of Gothenburg, the University of Linköping, and the University of Oslo.
Current research
Annie is currently a postdoctoral researcher at the Institute of Medicine and works on studies regarding diet and lifestyle factors and IBD. She is also involved in studies regarding diet and celiac disease, type 1 diabetes and LADA with researchers from Lund University and Karolinska Institutet. In 2027-2028, Annie will be working as a postdoctoral researcher at Massachusetts General Hospital to study how diet and physical activity influence inflammatory and non-inflammatory outcomes in individuals with IBD.
