Bakgrunn og aktiviteter

I am trained as a pharmacist M.Sc. in Pharmacy from the University of Copenhagen and received a Ph.D. in pharmacoepidemiology from University of Southern Denmark.

My research focuses on the clinical epidemiology and use of in its broadest sense, with a current focus on inflammatory bowel disease, urogynaecology and assisted reproductive fertility treatment. My expertise is register-based research using clinical and national health registers.  

Selected ongoing research

Does Disease Activity after induction Treatment with Anti–Tumor Necrosis Factor, Predict Short-Term Outcomes in Crohn’s Disease and Ulcerative Colitis?

How does disease control versus maintenance treatment strategy affect the prognostic impact of disease activity and the tolerance of anti-tumor necrosis factors?

Infertility treatment in women with chronic disease reproductive outcomes in women with inflammatory bowel disease.
