Research description

As a pediatric gastroenterologist, most of my clinical time is devoted to patients with inflammatory bowel disease (IBD). They are sometimes severely ill and require advanced treatments like nutritional treaments, medicines and sometimes surgery.

The knowledge gaps concerning IBD etiology and treatments are many. Which is the mechanism of the inflammatory suppression initiated of nutritional treatment in Crohn's disease? The connection between the IBD patients microbiota and immunological profile - what does it look like? Is nutritional treatments also an alternative in ulcerative colitis? Is it possible to change the microbiota with nutritional treatments?

My group work with translational studies concerning these questions. We investigate the clinical outcome of new nutritional treatments and if and how the microbiome and immunological profile in the mucosa, with focus on innate lymphocytes, may change after treatment.

The aim of my research is to improve the life and health of children and youth with IBD, and maybe the treatment recommendations may be changed if we can show if (and how) new ways of nutritional treatment is effective as induction of remission in IBD.
