Fruitful Circle U. research meeting in Paris

New collaborations and new opportunities for exchange of researchers were some of the results achieved when researchers from the Aarhus Research Group in Orthopaedic Surgery Epidemiology (AROSE) visited a research team at Université Paris Cité under the auspices of the Circle U. alliance.

AROSE is based at Department of Clinical Epidemiology at Aarhus University and led by professor Alma B. Pedersen. Along with two PhD students and a biostatistician, she recently visited Université Paris Cité to meet with a research group led by professor Remy Nizard. The two groups presented their research in orthopedics and exchanged ideas. Their topics of interest are similar but the two groups work in different ways in terms of methodology and data sources, as the research facilities in Denmark are unique due to the availability of health registry data. Alma B. Pedersen describes the meeting as a great success.

“The visit has resulted in new contacts, new ideas, and new insight about building international collaborations and bridging the gap between clinical work and research. We agreed to proceed with a new collaborative project, work together on funding applications, and include Dr. Jules Descamps from Paris as observer in the group of supervisors for one of our PhD students. In addition, we agreed to plan a research stay at Aarhus University for a PhD student from Paris”, says Alma B. Pedersen.

She adds:

“We would like to thank our colleagues from Paris for their genuine hospitality. Also, we would like to thank Erasmus for the ‘staff mobility, higher education’ grant. Without the support from Erasmus, the meeting in Paris would not have been possible and this new collaboration within the Circle U. alliance would not have been established”.


Circle U. is a European alliance of nine partner universities. The aim of the alliance is to promote internationalization and create new links between education, research, teaching, and innovation.


AROSE Professor Alma B. Pedersen’s research group, AROSE, conducts research within orthopedic surgery epidemiology and patient safety. In collaboration with her team, she is studying risk factors for and prognosis after complications such as reoperation, infection, thrombosis, and chronic opioid use occurring after surgery for, e.g., osteoarthritis in the hip or knee joint or hip fracture. In addition, she works on developing predictive models and algorithms for early detection of postoperative complications using Danish health registries.
