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 lead the research program 'Pelvic- and abdominal problems'. This includes the supervision of the following projects.
A randomized controlled trial comparing incontinence app to care as usual, for women with urinary incontinence in general practice.
