Having been a consultant pathologist for more than 25 years, subspecialized in GI- pathology, at the Department of pathology in Roskilde, I transferred in January 2022 to Center of Surgical Science, in a part time position.

2022- Consultant pathologist, CSS, Zealand University Hospital, Køge

1996 – 2021 Consultant pathologist, Department of Pathology, Zealand University Hospital, Roskilde

2006 – 2018 Associate professor Postgraduate Pathology, University of Copenhagen

1982 MD, Copenhagen University

2002 Master of Medical Education, Dundee

My research has been on Thymus, postgraduate education in the specialty of pathology, microscopic colitis.
