Research interests

As a general practitioner and epidemiologist, my previous works were mainly on urological research, especially the epidemiology of male lower urinary tract symptoms (including nocturia), and prostate cancer screening in general practice. 

Currently, I am the programleader of the research program 'Pelvic- and abdominal problems in general practice'. This includes the following projects.

  • URinControl
