Research description

Ongoing research

Celiac disease

Most of my papers in this field have been epidemiological, although I have published papers on experimental research in celiac disease.

Teaching portfolio

I enjoy teaching and my teaching was first externally peer reviewed in 2004 and I was found to have ”very good educational skills”.

Topics that I frequently discuss in my lectures are: evidence-based medicine (EBM)/epidemiology, celiac disease, emergency paediatrics, and Swedish national health registries (including the personal identity number).

I have also written several books and book chapters, e.g."Att börja forska - inom medicin, bio- och vårdvetenskap" (Studentlitteratur 2002 and second edition in 2015), "Doktorns guide till gluten" (Volante 2016) and "Barnläkarens guide" (2020)
