Current research interests
Celiac disease is my main research interest. Most of my papers in this field have been epidemiological, although I have published papers on experimental research in celiac disease. Lately, I have spent considerable time coordinating an international group of scientists working on new guidelines for the definition and management of celiac disease.

I have been a member of the steering board of the Swedish IBD register since 2005, and in the past years I have responsible for the annual report. I am currently coordinating one validation of inflammatory bowel disease diagnoses (Crohn’s disease and ulcerative colitis), and a second validation of microscopic colitis. Together with former PhD student Ola Olén, I coordinate a project on complications in IBD, with focus on cancer. I am one of three team leaders for the project "Scandinavian CANcer-in-Inflammatory Bowel Disease study" (SCAN-IBD). In addition, I am supervising two postdocs in Britain working on cancer complications and diverticulitis. Furthermore I work closely with Professor Hanns-Ulrich Marschall, on intrahepatic cholestasis during pregnancy (ICP).

Research priorities
Pathways and mechanisms: Cumulative and additive social risk exposures (e.g. transient v. persistent poverty). Stress and allostatic load. Social into the biological and epigenetic. | Methodological issues: Methods for examining change over time including longitudinal effects studies. Regional studies (within countries).
