Postdoctoral Fellow, Department of Surgery

Dr. Dabekaussen is a graduate from the University of Groningen in the Netherlands and completed her clinical rotations in the Netherlands and Germany.

She completed part of her PhD at Brigham and Women’s Hospital in 2019 and will defend her thesis later this year. She also holds a master honours degree in leadership from the University of Groningen.
