Research

-------- Academic interests --------------------------------------------------
* Bowel cancer
* Epidemiology - methods
* Celiac disease
* Screening
* Registry and big data research
* Causal inference
* Statistical analysis
* Clinical research
My research interests spans a broad range of topics within medicine,
reflecting my clinical background as a specialist in general practice. I am
particularly interested in epidemiological methodology, causal inference and
spent my postdoc time with the causal inference group at Harvard School of
Public health. I have extensive experience from big data analyses such as
Swedish quality register, national health care registers and the American
SEER-Medicare registers.

Teaching

I teach in the MD program module 8 and I am also responsible for a 2-week
elective class (MED3051) at University of Oslo. Further, I also teach EBM and
research methodology at the MD programme at the Karolinska Institute in
Stockholm. Recently I published a postgraduate tutorial methodology paper on
how to emulate a randomized trial using observational data in SAGE research
methods cases
