Her clinical work is affiliated with Region Sjælland's pediatric services, as indicated by her institutional email domain. She maintains an active research profile with 41 documented publications spanning clinical trials, epidemiological studies, and systematic reviews.

Her research focuses primarily on pediatric infectious diseases, with particular expertise in post-pandemic infection patterns, streptococcal diseases, Mycoplasma pneumoniae, and gastroenteritis epidemiology. Recent work demonstrates how the COVID-19 pandemic disrupted typical childhood infection cycles, leading to unusual surges in conditions like invasive group A streptococcal infections and Mycoplasma pneumoniae among Danish children. Her research employs nationwide cohort methodologies and randomized controlled trials to evaluate treatment protocols for common pediatric conditions.
