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: grant writing, scientific misconduct, celiac disease, emergency paediatrics, international health, Swedish national health registries (including the personal identity number), and questionnaire research.
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), and "Doktorns guide till gluten (Volante 2016)
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:
- The Oslo definitions for coeliac disease and related terms. Ludvigsson JF, Leffler DA, Bai JC, Biagi F, Fasano A, Green PH, et al Gut 2013 Jan;62(1):43-52
Celiac disease was also the topic for my Fulbright Research Scholarship at the Mayo Clinic (Rochester, Minnesota, USA) in 2012.
I am the coordinator and lead author of one of the world's largest gastrointestinal cohort studies: ESPRESSO (Epidemiology Strengthened by histoPathology Reports in Sweden).
I addition I have been a member of the steering board of the Swedish IBD register since 2005, and responsible for their annual report.
Among the five most work-intense papers of my career is a validation and review of the Swedish Inpatient Register:
- External review and validation of the Swedish national inpatient register. Ludvigsson JF, Andersson E, Ekbom A, Feychting M, Kim JL, Reuterwall C, et al BMC Public Health 2011 Jun;11():450
My other research mainly concerns vaccination and child health:
A) H1N1 immunization and pregnancy outcome (coordinator). This project, funded by the Swedish Research Council as well as by the funding agencies "FORTE" and the Swedish Society of Medicine, has yields several high impact publications.
B) I have been involved in the ABIS study (All Babies in southeast Sweden) since the late 1990s. My thesis, consisting of 5 papers and 1 research letter, was based on this study.
The ABIS study is a longitudinal study that was initiated in 1997. It includes the collection of blood specimens and other tissues, as well as questionnaire data.
